0.15mm Double Layer
HTV+PC Material
120 Pieces
Blue Base Plate
I have used DUROCK switch films on more builds than I can count, and the 0.15mm HTV+PC version remains my go-to recommendation for most setups. The double-layer construction combines HTV rubber with a polycarbonate backing, giving you the best of both worlds: some compressibility from the rubber and structural support from the PC layer.
What makes these films stand out is the thickness. At 0.15mm, they fit most MX-style switches without causing housing closure issues. I have installed them on Gateron Yellows, Durock T1s, and Cherry MX Blues with no problems. The blue base plate makes alignment easy during installation, which is helpful when you are filming 70 switches in one sitting.

The sound improvement is noticeable. My test keyboard with stock Gateron Yellows went from a slightly hollow clack to a deeper, more satisfying thock. The films reduce that metallic spring ping that many switches have out of the box. If you have ever heard that annoying ringing sound after bottoming out, these films help dampen it significantly.
One thing to note: these films address housing wobble, not stem wobble. If your switch has side-to-side play when you wiggle the stem, films will not fix that. But if the top and bottom housings feel loose relative to each other, these films tighten that gap and create a more solid feel.

This film is ideal for enthusiasts who want reliable performance across different switch types. The 0.15mm thickness works well for switches with average tolerances, including most Gateron, Cherry, and Durock switches. If you are new to switch modding and want something that will not cause fitment headaches, this is the safest choice.
Beginners may find the installation tedious. You need to open each switch, place the film correctly, and close it without shifting the film. Budget extra time for your first few builds. Also, if your switches have very tight tolerances, even 0.15mm might be too thick.
0.3mm Foam Thickness
45% Compressive Rate
120 Pieces
Black Color
The 0.3mm foam version from DUROCK is designed for switches with looser housing tolerances. The foam has a 45% compressive rate, meaning it squishes down from 0.3mm to about 0.165mm when compressed. This gives it more range to fill larger gaps between switch housings.
In my testing, these films produced the deepest sound profile of any foam-based film I tried. If you are chasing that deep thock sound that keyboard sound tests love, this thickness gets you closer. I tested them on older Gateron switches that had noticeable housing wobble, and the improvement was substantial.
However, I did run into some quality issues. The foam is delicate, and I tore several films while removing them from the backing sheet. The die-cut quality is not as clean as the HTV+PC version, which led to some frustration during installation. You definitely want to use tweezers and take your time.
These thick foam films work best for older switches or budget switches with known loose tolerances. If you can feel the top housing wobble when you squeeze your switches, the 0.3mm foam will help tighten things up. They are also a good choice if you prioritize sound depth over ease of installation.
The fragile nature of the foam means you will likely waste some films during your build. I recommend ordering extra if you are doing a full keyboard. These also will not work well with tight tolerance switches like Akko or some newer JWK molds. The thickness can prevent the housing from closing properly.
0.5mm Poron Foam
Mild Adhesive Backing
120 Pieces
RGB Compatible
These Poron switch pads from DUROCK take a different approach than traditional switch films. Instead of going between the top and bottom housings, these pads sit between the switch and the PCB. This means you can use them on hotswap keyboards without disassembling your switches.
I tested these on a Keychron Q1 with Gateron G Pro switches, and the installation was straightforward. The mild adhesive backing keeps each pad in place while you seat the switch. The pads have cutouts that allow RGB light to shine through, which is important if your build uses per-key lighting.
The sound improvement is more subtle than traditional films. The pads reduce the hollow echo that some keyboards have, especially those with aluminum plates. They essentially decouple the switch from the PCB, which changes the resonance characteristics of the board.
These pads are perfect for hotswap keyboard owners who want to improve their sound profile without desoldering or opening switches. If you have a prebuilt keyboard with RGB and want a quick mod, this is your best option. They also work well for people who find traditional films too tedious.
The improvement is not as dramatic as traditional switch films. If your switches have significant housing wobble, these pads will not fix that issue. They are more about overall board acoustics than individual switch feel. Also, the installation takes time since you need to place a pad for every switch position.
0.3mm Poron Thickness
120 Films
Includes Anti-Static Tweezers
2 Year Warranty
The Ranked Premium kit is one of the few options that includes installation tools. You get 120 Poron films plus a pair of anti-static tweezers, which makes the whole process easier. Having the right tweezers for switch filming is surprisingly important, and this kit saves you from buying them separately.
The 0.3mm Poron thickness strikes a balance between the thin 0.15mm films and the thick foam options. In my testing, this thickness worked well with most standard Gateron and Cherry switches. The Poron material compresses slightly under pressure, which helps it conform to slight variations in housing tolerances.

Sound-wise, these films deliver that classic Poron warmth. My test build with KTT Kang Whites went from a bright clack to a more rounded, deeper sound. The change was noticeable but not as dramatic as I have experienced with some premium films from Deskeys or TX.
My main complaint is the backing sheet. The films are die-cut into the sheet but not fully punched through, making them difficult to remove cleanly. I ripped several films trying to get them off, which is frustrating when you are working through a full keyboard build.

This kit is great for first-time builders who want everything in one package. The included tweezers are genuinely useful, and the compatibility with most MX-style switches means you will not run into fitment issues with common switches. It is a safe choice for learning the filming process.
If you already have good tweezers, you are paying extra for a tool you do not need. The film quality is solid but not exceptional. Experienced builders might prefer to buy films and tools separately from higher-end brands.
0.5mm Poron Memory Foam
120 Pads
Non-Stick Adhesive
Includes Tweezers
These YIMAGUJRX pads are similar to the DUROCK Poron pads but with better die-cut quality. The pads come on a clean sheet with no leftover punch debris, which means you will not have little foam bits falling into your keyboard. This attention to detail matters when you are doing a clean build.
I tested these on a hotswap keyboard with Kailh Box switches. The installation was painless since I did not need to open any switches. I just placed each pad on the PCB hotswap socket and pressed the switch in. The non-stick adhesive holds well but allows repositioning if you make a mistake.

The sound improvement focuses on removing that hollow, echoing quality that some keyboards have. My test board had a noticeable ping on certain keys, and these pads eliminated most of it. The typing sound became more focused and less scattered.
At roughly 10 cents per pad, the value is excellent. You get 120 pads plus tweezers, which is enough for a full-size keyboard with extras for mistakes. The high-density memory foam holds up well over time and does not seem to compress permanently.

These pads excel on hotswap keyboards where you want quick acoustic improvements. They are perfect for gamers or typists who want better sound without spending hours disassembling switches. The reusability feature is nice if you like to experiment with different configurations.
These only work with hotswap keyboards. If your switches are soldered to the PCB, you cannot use these without desoldering everything first. Also, the pads add a small amount of height, which might affect keycap clearance in very tight builds.
0.18mm Single Layer
2400 Pieces Total
HTV+PC Material
Clear White Color
If you are planning multiple keyboard builds or running a keyboard building service, this bulk pack from YMDK offers incredible value. With 2400 films in one package, you could film approximately 20 full-size keyboards. That works out to a fraction of the cost per switch compared to smaller packs.
The single-layer HTV+PC construction is similar to other budget films. At 0.18mm thickness, they are slightly thicker than the 0.15mm DUROCK films but still thin enough for most switches. The clear white color is neutral and will not clash with any build aesthetic.
In my testing, these films performed as expected for their price point. They reduced housing wobble on my test switches and added some depth to the sound profile. They are not as refined as premium films, but they get the job done for budget builds.
This bulk pack is ideal for keyboard enthusiasts who build frequently or mod switches for friends. If you know you will be filming dozens of keyboards over time, the cost savings are significant. It is also great for anyone who tends to waste films during installation and wants plenty of extras.
The quality is not as consistent as premium brands. Some films had slight variations in thickness, which could affect switch feel. These are also not compatible with low-profile switches or box switches, so check your switch type before ordering.
84 Layout PCB Foam
120 Switch Pads
Includes Prying Bar and Tweezers
High Density Poron
The RunJRX 84 Layout Kit provides a comprehensive sound dampening solution for TKL and compact keyboards. You get Poron PCB foam cut for an 84-key layout, 120 switch pads, a plastic prying bar, and tweezers. It is essentially everything you need for a complete acoustic overhaul.
I tested this kit on a Keychron K8 Pro, and the modular design made installation straightforward. The PCB foam fits the standard TKL layout well, with cutouts in the right places. The switch pads have adhesive backing and are easy to position on each hotswap socket.

The combined effect of the PCB foam and switch pads is substantial. My test keyboard went from a somewhat hollow, metallic sound to a much deeper and more satisfying thock. The typing experience felt more premium, with less vibration traveling through the case.
The included tools are genuinely useful. The prying bar helped me remove keycaps and switches without damage, and the tweezers made placing the switch pads much easier. Having everything in one package saved me from hunting for tools.

This kit is perfect for anyone with an 84-key or TKL keyboard who wants a complete sound improvement solution. If you have been disappointed by individual mods that did not make much difference, combining PCB foam with switch pads often produces more noticeable results.
Not all 84-key keyboards have the same layout. You may need to trim the foam slightly to fit your specific board. Also, the foam thickness can cause issues with case closure on some keyboards, so check your available space before installing.
96 Layout PCB Foam
120 Switch Pads
Includes Prying Bar and Tweezers
High Density Poron
The 96 Layout version of the RunJRX kit is designed for compact full-size keyboards. These 96-key boards have become increasingly popular because they offer a numpad in a smaller footprint. This kit gives you the same comprehensive sound dampening as the 84-layout version but sized correctly for these boards.
I installed this on an Epomaker AK84S, and the fit was nearly perfect. The modular foam design means the pieces fit around the stabilizers and other components without blocking switch positions. The 120 switch pads were enough for the entire board with a few extras.

The sound transformation was impressive. My test keyboard had a characteristic metallic ring on the larger keys, particularly the spacebar and enter key. After installing the kit, those rings disappeared, replaced by a solid, deep sound that makes typing more satisfying.
One thing I appreciate about this kit is the quality of the Poron. It is high-density with a micro-fine cell structure, which means it dampens sound without absorbing moisture or degrading over time. The manufacturer claims a 2-3 year lifespan, which matches my experience with similar materials.

This kit is ideal for 96-key or 100-key keyboard owners who want maximum sound improvement. If you use a compact full-size board and find the sound too hollow or pingy, this combination of PCB foam and switch pads will make a noticeable difference.
Some 96-key boards have non-standard layouts that may require trimming the foam. I had to cut small sections around the arrow keys on my test board. Also, if your case has limited internal space, the added foam thickness might make reassembly difficult.
68 Layout Gasket Foam
2-Piece Set
EVA Material
Soft Sponge Construction
The Mintcaps 68 Layout foam takes a different approach than the RunJRX kits. Instead of separate PCB foam and switch pads, this is a 2-piece gasket that sits between your PCB and the plate or positioning board. It is designed specifically for 65% keyboards with a 68-key layout.
I tested this on a Tofu65 build, and the installation was simple. The foam sheets sit on top of the PCB before you install the plate. The cutouts for switches are generous, which makes alignment easier but can allow some pieces to shift during assembly.

The sound improvement focuses on reducing the hollow resonance that 65% keyboards often have. My test build went from a slightly echoey clack to a more contained, deeper sound. The difference was subtle but noticeable, especially when typing at speed.
One issue I encountered was the foam arriving folded in the package. It took a day of pressing it flat under some books before it would lay properly in the keyboard. This is a packaging problem that could be easily fixed but added frustration to the installation.

This foam is a good choice for 65% keyboard owners on a budget. If you want to improve your keyboard sound without spending much, this 2-piece set provides decent value. It is especially useful for boards that do not have space for switch pads.
The quality control is inconsistent. Some users report the cutouts being in the wrong positions for their specific board. The gasket material can also pop out of switch holes during assembly, requiring you to reposition it multiple times.
20 Silicone PCB Pads
12 Stabilizer Wire Pads
Teflon and Silicone Options
Cherry Profile Compatible
This YIMAGUJRX set targets a different problem than the other products in this list. Instead of switch films, these are stabilizer films designed to reduce rattle and noise from your spacebar, shift keys, and enter key. The set includes 20 silicone PCB satellite switch buffer pads and 12 stabilizer steel wire EVA pads.
I have always found stabilizer tuning to be one of the most impactful mods for keyboard sound. These films go between the stabilizer housing and the PCB, providing a cushion that absorbs impact and reduces rattle. The wire pads go under the stabilizer wire where it contacts the PCB.
In my testing on a keyboard with stock Cherry stabilizers, these films made a noticeable difference. The spacebar went from a rattly, inconsistent sound to a much cleaner thock. The silicone material is softer than the Teflon option, which produces a duller but deeper sound.
This set is perfect for anyone whose keyboard has rattle in the stabilized keys. If your spacebar or shift keys sound inconsistent or rattly, these films will help. They are especially useful for prebuilt keyboards where you cannot easily replace the stabilizers.
These only work with PCB-mounted stabilizers, not plate-mounted ones. The films are also difficult to remove from the backing without tweezers. The Teflon option is thicker than some people prefer, so I recommend the silicone for most builds.
Switch films are thin pieces of material that go between the top and bottom housings of mechanical keyboard switches. They act as gaskets, filling the small gap that exists between the two halves of the switch housing. This gap is what causes housing wobble and contributes to rattly switch sounds.
When you press a key, the force travels through the switch stem into the housing. If the top and bottom housings are loose, that energy dissipates as vibration and rattle. Films create a tighter seal, keeping the energy focused and producing a cleaner, deeper sound.
The three main materials used for switch films are polycarbonate (PC), Poron foam, and HTV rubber. PC films are rigid and provide consistent results across different switches. Poron is compressible foam that conforms to slight variations in housing tolerances. HTV rubber sits somewhere in between, offering some compressibility while maintaining structure.
For most builds, I recommend starting with PC or HTV+PC films like the DUROCK 0.15mm option. These provide reliable results without the variability of foam. Poron films like the Ranked kit work well if your switches have slightly looser tolerances or if you want a warmer sound profile.
Thickness is arguably the most important factor when choosing switch films. Thinner films (0.15mm) work with tight tolerance switches and are less likely to cause fitment issues. Medium thickness (0.3mm) suits average switches with moderate housing play. Thicker options (0.5mm) are best for loose housings or as PCB pads rather than traditional films.
The safest approach is to start with 0.15mm films if you are unsure about your switch tolerances. You can always try thicker films later, but starting too thick can damage switches or prevent housings from closing properly.
Switch films help when your switches have noticeable housing wobble. To test this, hold the switch between your fingers and try to wiggle the top housing relative to the bottom. If you feel movement, films will help. They are also useful for sound tuning if you want a deeper thock profile.
However, films are not always necessary. Modern switches from brands like Gateron and Durock often have tight tolerances that do not benefit from filming. Some users report damaging tight switches by forcing films into them. If your switches already feel solid and sound good, filming might not be worth the effort.
Most switch films are designed for MX-style switches, which covers the majority of mechanical keyboard switches including Cherry, Gateron, Kailh, and Durock. However, compatibility varies based on specific switch molds and tolerances.
Gateron switches generally benefit from films, especially older batches. Cherry MX switches have varied tolerances depending on the generation. JWK and Durock switches usually have tight tolerances and may not need films. Always test one or two switches before filming your entire keyboard.
Yes, switch films make a noticeable difference when your switches have housing wobble. They tighten the gap between top and bottom housings, reducing rattle and deepening the sound profile. However, if your switches already have tight tolerances, the improvement may be minimal.
For most switches, 0.15mm films are the safest starting point. Use 0.3mm films for switches with loose housings or if you want more sound dampening. Avoid films thicker than 0.3mm unless your switches have significant tolerance issues.
Yes, but you need to open each switch to install traditional films. Alternatively, you can use PCB switch pads like the DUROCK Poron pads or YIMAGUJRX pads, which go between the switch and PCB without requiring switch disassembly.
No, switch films reduce housing wobble, not stem wobble. Stem wobble is the side-to-side play of the switch stem itself, which is a different issue. Films only address the gap between the top and bottom housing halves.
It depends on the material. Polycarbonate films can sometimes be reused if removed carefully, though they may not seat as well the second time. Foam films like Poron compress during use and generally do not perform as well if reused. It is best to use fresh films for each build.
Finding the best switch films for mechanical keyboards comes down to matching the right thickness and material to your specific switches. For most builders, the ZugGear DUROCK 0.15mm HTV+PC films offer the best balance of compatibility and performance. If you want a complete solution with tools included, the RunJRX Poron kits provide excellent value. And for hotswap keyboard owners who want quick results, the PCB pads from DUROCK and YIMAGUJRX let you improve your sound without disassembling switches.
Remember that switch films are just one part of keyboard sound tuning. Lubing your switches, adding case foam, and tuning your stabilizers all contribute to the final result. Start with films if your switches have housing wobble, and build from there. Happy modding.
