Keycap material affects how your keyboard feels, sounds, and holds up over time, but most people don't think about it until they're already shopping.
PBT and ABS are the two dominant keycap plastics, and they behave very differently.
This post compares them based on feel, sound, and durability so that you know which is better for you.

What Are ABS Keycaps?
ABS is the default material for many keycaps since they're cheaper to produce, easier to dye, and have a smoother feel out of the box.
The main problem is shine. Heavy typists typically see shine within 3-6 months, and lighter users closer to 12.
ABS keycaps have a slightly higher-pitched sound than PBT; it can sound "clacky" on thinner sets.
ABS isn't bad, but it has its trade-offs. It's great for budget builds and RGB-focused setups.
What Are PBT Keycaps?
PBT has a slightly rougher, grainier surface than ABS. Most typists prefer the texture for long typing sessions.
PBT's main advantage is the shine resistance. With normal use, it can last years without visible shine.
It also has a generally deeper and more "thocky" sound compared to ABS.
The trade-offs with PBT is that it has fewer colorway options than ABS, and quality control varies at budget price points.
PBT sets typically cost more than ABS, though the durability usually justifies it in the long-term.
PBT vs ABS Keycaps
Quick Comparison Table
| ABS | PBT | |
|---|---|---|
| Surface feel | Smooth, slippery | Grainy, textured |
| Sound profile | Higher-pitched, clacky | Deeper, more muted |
| Shine resistance | Low (3–12 months) | High (years) |
| Colorway options | Wide variety | More limited |
| Price | Lower | Higher |
| Best for | Budget builds, RGB setups | Daily use, enthusiast builds |
Surface Feel
ABS is smoother and more slippery, while PBT is grainier and offers more tactile feedback on the surface itself. Neither is better; it comes down to preference.
Sound Profile
ABS tends to sound higher-pitched and clacky, while PBT is deeper and more muted.
Remember that switches will have a far greater impact on sound than keycap material alone.
PBT vs ABS Keycaps: Longevity
The main difference for longevity is that ABS develops shine much faster than PBT.
With ABS, the oils from your fingers gradually smooth out the surface texture over time. This is also why oily hands accelerate the process.
With normal use, PBT can last the lifetime of a keyboard without visible shine.
Legend durability also varies. Double-shot legends on PBT are essentially permanent, while dye-sub legends on ABS can fade alongside the shine.
If you type heavily or have oily hands, PBT is the better long-term choice. If you swap keycaps frequently, ABS shine matters less.
Is PBT or ABS Better for Your Setup?
There's no universal answer. The right choice depends on your situation. Here's a quick breakdown by use case.
Quick Recommendation Table
| Use Case | Keycap Material |
| Gaming | ABS if you plan to swap keycaps often; otherwise PBT |
| Heavy Typing | PBT for the shine resistance and texture |
| Budget Builds | ABS for the lower price points |
| RGB-Focused Builds | ABS. The smoother surface looks better with RGB |
Gaming
ABS is fine for gaming since shine is less of an issue with intermittent use.
If you plan to keep the same keycaps long-term, PBT is the better investment; otherwise it comes down to feel and sound preference.
Heavy Typing
PBT is the clear winner. The shine resistance and texture make a real difference over long typing sessions.
Budget Builds
ABS is better for budget builds due to the lower price points. If you're not bothered by shine, there's no reason to upgrade.
RGB-Focused Builds
ABS is the best for RGB builds. It has a wider colorway availability and can look better under RGB lighting due to its smoother surface.
Conclusion
PBT is the best long-term material, while ABS is better for budget builds, RGB builds, or people who plan to swap keycaps often.
Whichever you choose, keycap material is one of the easiest upgrades you can make to improve how your board feels and sounds over time.

FAQ
Are PBT keycaps worth the extra cost?
Yes for daily use and long-term builds. The shine resistance and texture hold up far better over long use.
They're less worth it if you swap keycaps frequently or are on a tight budget.
Do ABS keycaps always develop shine?
Yes, eventually; it's a property of the material.
The time it takes varies by typing intensity and hand oils, but it's inevitable. Some people don't mind it; others find it a dealbreaker.
Can I put PBT keycaps on any mechanical keyboard?
Yes, as long as the stem type matches (MX-style is the most common). Hot-swap boards make this especially easy since you're already set up to customize.
What keycap material do most enthusiasts use?
PBT is the enthusiast standard. The texture, durability, and sound profile make it better for serious builds.
Does keycap material affect typing sound?
Yes, but less than switches, board, and foam.
PBT tends toward deeper and more muted; ABS toward higher-pitched and clacky.
