Why this product type matters
ABS (Acrylonitrile Butadiene Styrene) and PBT (Polybutylene Terephthalate) are the two most common plastics used for keycaps.
- Feel & Texture: ABS caps are smooth and often have a glossy finish, but they can become shiny with use. PBT caps have a slightly textured, matte feel that resists shine.
- Durability: PBT is more resistant to wear, UV light, and heat, meaning legends are less likely to fade. ABS can develop a "shiny" patina and the legends may wear off faster, especially with dye‑sublimated or laser‑etched designs.
- Sound: ABS tends to produce a higher‑pitched “clack,” while PBT delivers a deeper, more muted thock, which many typists prefer for quieter typing sessions.
- Manufacturing & Design Options: ABS is easier to mold, allowing for intricate sculpted profiles and a wider variety of colors. PBT is harder to mold, so many PBT sets use dye‑sublimation for legends, which limits color variety but offers crisp, long‑lasting graphics.
- Price: ABS keycaps are generally cheaper, while high‑quality PBT sets often command a premium.
Understanding these differences helps you choose a set that matches your typing style, aesthetic preferences, and budget.
How to choose
-
Determine your priority – If you value long‑term legend durability and a matte feel, lean toward PBT. If you want a glossy look, a wide color palette, or a lower price, ABS may be better.
-
Check the profile – The material doesn’t dictate profile, but many popular profiles (Cherry, OEM, SA) are offered in both. For example, the Womier Pink Shine Through Keycaps use PBT with a Cherry profile, providing a tactile feel while staying durable.
-
Look at manufacturing method – Dye‑sublimation (common on PBT) gives crisp, fade‑proof legends. Double‑shot (available on both ABS and PBT) embeds the legend in the plastic for extra durability. Laser‑etched works mainly on ABS and may wear faster.
-
Consider sound & typing experience – If you type loudly, PBT’s thock may reduce echo. For a sharper sound, ABS might be appealing.
-
Match your keyboard layout – Verify that the set covers the number of keys you need (e.g., 118‑key full‑size, 60%, 65%). The PBT Keycap Set 118 Keys/Set 8008 offers full‑size coverage, while the Key Caps for Mechanical Keyboard Height Replacement covers only a portion of keys.
-
Budget – Expect PBT sets like the Womier Pink Shine Through (≈$26) to be modestly priced, while specialty sets (artisan resin caps, e.g., the Keycap Resin Artisan KOI Fish) can be higher cost per piece.
-
Read reviews and ratings – A higher rating (e.g., 4.5/5 for the KOI Fish artisan caps) indicates satisfaction with material quality and finish, though artisan caps are decorative rather than functional for full‑set replacement.
By weighing these factors, you can select a keycap set that aligns with your typing habits, visual style, and budget.

Frequently Asked Questions
Will ABS keycaps become shiny over time?
Yes, ABS caps tend to develop a glossy shine after repeated keypresses because the surface wears down. This is less common with PBT caps, which retain a matte texture longer.
Are PBT keycaps always more expensive than ABS?
Generally, high‑quality PBT caps cost more due to the material and manufacturing process, but there are budget‑friendly PBT options. Conversely, premium ABS sets with double‑shot legends can be priced similarly to mid‑range PBT sets.
Can I mix ABS and PBT keycaps on the same keyboard?
You can mix them if the heights and profiles match, but the differing texture and sound may be noticeable. For a cohesive feel, most users stick to one material throughout the set.
Do PBT keycaps affect the sound of my keyboard significantly?
PBT caps tend to dampen the higher‑frequency clack of a keyboard, resulting in a deeper, quieter thock. The effect is noticeable but also depends on the switch type and case material.
Is dye‑sublimation only used on PBT keycaps?
Dye‑sublimation works best with PBT because the porous surface absorbs the ink. While it can be applied to ABS, the results are usually less durable and vibrant.
