Keycaps are a small cover, usually made of plastic (though we’ve found some unusual materials that may pique your interest), placed over a key switch of a mechanical keyboard. Check out switches matter for more on switches.

Keycaps are the face of your keyboard, and have a great impact on the comfort level, the feel, and the overall typing or gaming experience.

Keycap Material

The material used to create a keycap can make a huge difference to how it feels and performs. Keycaps are generally made of plastic, but there are some other less common materials that are used.

Now, you must be wondering ‘what is the best keycap material?’

Best Keycap Materials

ABS and PBT are the two most common materials that are used to create keycaps. I’ll explain the differences, and also bring some alternatives to your attention!

All keycaps discussed here have strong compatibility towards Cherry MX switches and clones.

Now, let’s discuss ABS vs PBT.

ABS (Acrylonitrile Butadiene Styrene)

Welcome to Chemistry Class

ABS is a thermoplastic, meaning, it can melt at low-temperate and can easily be molded.


·       ABS Keycaps are completely recyclable which makes them environmentally friendly.

·        ABS keycaps are extensively used because they are inexpensive and are manufactured easily.

·       ABS keycaps have a smooth texture when your fingers slide over them.

·       Makes less noise while typing.

Usually, mechanical keyboards come with inexpensive ABS keycaps that are thin and seem fragile to use.

But recently, there have been advancements and GMK Keycaps have stolen the show. They are pricier than regular ABS keycaps but every penny is worth it!

GMK keycaps are the best ABS keycap you’ll lay your hands on.


  • Develops a shiny texture when used for years.
  • Lettering wears off due to excessive usage.
  • Thin and non-durable.

PBT (Poly Butylene Terephthalate)

PBT is a less frequently used keycap material because it is costly. It has smoother texture than ABS and is robust towards use.


·       PBT is also a thermoplastic and can also be recycled.

·       PBT has a textured feel when touched due to its matte finished appearance.

·       Moreover, PBT has high impact resistance, which means it can endure all kinds of aggressive gaming and typing pressures.

Just like GMK (ABS), PBT has something to offer too- EPBT (Enjoy PBT)!

epbt keycaps

ebpt keycaps stand for Enjoy pbt, which is a Chinese manufacturer. They are considered among the best in class of Chinese manufacturers of keycaps. They use pbt keycaps in their sets and boards. When buying a pbt keycap set it is better to go with an established vendor such as ebpt due to greater quality control. This is great for helping ensure you stay away from pbt keycap sets that may have warping problems.

Ebpt are a great choice when it comes to keycaps made using the pbt material.

GMK ABS Keycaps vs EPBT PBT Keycaps

Comparing Alignment/tooling and visual appearance of the top ABS keycap and PBT keycap manufacturers

PBT Keycaps are often considered a better typing experience- the consensus is that they have a bit more of a solid quality feel, and have the benefit of robustness of the harder plastic.

However, premium abs manufacturers such as GMK may have a slight upper hand in terms of key alignment, die quality and lettering precision- so if these factors are a concern it may be better to go the ABS keycap route with GMK. Or, check out Signature Plastics PBT keycaps. EBPT are considered to have some of the best lettering of Chinese PBT manufacturers, so their legends are still pretty nice though.

Conclusion- what’s the best keycap material?

Between ABS and PBT it’s tricky to place one over the other as both ABS and PBT have a lot to offer.

ABS is a cheap but efficient material to be manufactured, while PBT is expensive but has better durability. One common thing is that both of them are made of plastic and are conducive to recycling.

Transforming your mechanical keyboard into something that’s outstanding and pleasing to the eyes is a good move.

Just keep in consideration the comfort and best suited profile in mind when buying a new keycap set.

Try to invest in higher quality abs keycaps as lower quality ones can be thin and become greasy- higher quality keycaps are often double shot (added layer of lettering) which can help with the lifespan of the lettering.
