Ask any mechanical keyboard enthusiast about keycap materials, and you’ll get passionate answers. PBT vs ABS is one of the most debated topics in the keyboard community — and for good reason. The material your keycaps are made from affects sound, feel, durability, and price.
Let’s settle the debate.
The Short Answer
· Choose PBT if you want a textured, matte surface that stays looking new for years and prefer a deeper, “thockier” sound.
· Choose ABS if you want vibrant colors, smooth feel, and don’t mind the eventual shine that comes from months of use.
But there’s more to it than that.
PBT Keycaps: The Modern Standard
PBT (Polybutylene Terephthalate) is a crystalline plastic that’s harder and denser than ABS. It’s become the go-to recommendation for anyone looking to upgrade their keyboard.
Sound Profile
PBT keycaps produce a lower-pitched, “thocky” sound compared to ABS. The thicker walls and denser material dampen higher frequencies. Many enthusiasts specifically seek out PBT for this deeper acoustic profile.
Texture and Feel
Out of the box, PBT keycaps have a grainy, matte texture that provides excellent grip — especially noticeable if your fingers get sweaty while typing or gaming. This texture lasts. Even after a year of daily use, PBT keycaps maintain their matte finish.
Durability
PBT wins in longevity. It’s more resistant to:
· Heat and UV exposure
· Impact and cracking
· The “greasy shine” that develops on ABS
Drawbacks
PBT isn’t perfect. It’s harder to mold, which means:
· Limited color compatibility with double-shot manufacturing
· Slightly higher price point
· Warping can occur in cheaper sets
ABS Keycaps: The Classic Choice
ABS (Acrylonitrile Butadiene Styrene) has been the standard for decades. The vast majority of stock keyboards — even premium ones — come with ABS keycaps.
Sound Profile
ABS keycaps produce a higher-pitched, “clacky” sound. This is the classic mechanical keyboard sound most people grew up with. Some typists prefer this brighter acoustic signature.
Texture and Feel
Fresh ABS keycaps feel smooth and slightly silky. However, after 3–6 months of regular use, the oils from your fingers will begin polishing the surface. This “shine” is cosmetic only — the keycap still works fine — but many enthusiasts find it visually unappealing.
Color and Design
ABS is easier to mold and accepts more vibrant color pigments. This is why the most colorful, visually striking keycap sets (like GMK and SA sets) are made from ABS. If you want bright, saturated colors and complex designs, ABS is currently the superior material for that.
Cost
ABS is cheaper to produce. A decent PBT set costs $30–60 while entry-level ABS sets start around $15–25. However, high-end ABS sets (GMK, Signature Plastics) can cost $100–200+.
Head-to-Head Comparison
| Feature | PBT | ABS |
| Surface Texture | Matte, grippy | Smooth, can become shiny |
| Sound | Deeper (thock) | Brighter (clack) |
| Durability | Excellent — no shine | Moderate — develops shine |
| Color Options | Good, but limited bright colors | Excellent — vibrant and varied |
| Price (entry) | $25–50 | $10–30 |
| Price (premium) | $50–120 | $100–200+ |
| Weight | Heavier | Lighter |
| Shine Over Time | Minimal to none | Noticeable after 3–6 months |
The Myth: “PBT Is Always Better”
Here’s the thing: PBT is not automatically better than ABS. High-quality ABS sets from manufacturers like GMK, JTK, and Signature Plastics are beloved by the community for their crisp legends, perfect color matching, and surprisingly good durability.
The shine issue on ABS is real, but:
· Some people actually prefer the smooth, polished feel of shined keycaps
· High-end ABS takes much longer to develop shine than cheap ABS
· Washing ABS keycaps can restore some of their original texture
Meanwhile, cheap PBT keycaps can have problems too:
· Warped spacebars
· Inconsistent wall thickness
· Faded or poorly printed legends (especially on dye-sub sets)
Which One Should You Buy?
Choose PBT if:
· You want keycaps that still look new after a year
· You prefer a deeper, thockier typing sound
· You have sweaty or oily fingers (PBT’s texture helps significantly)
· You want a “set it and forget it” upgrade
Choose ABS if:
· You want specific vibrant colorways (especially GMK or SA profiles)
· You’re on a tight budget and can’t afford quality PBT
· You prefer the smooth, classic clacky feel
· You don’t mind replacing keycaps eventually
The Best of Both Worlds
Some manufacturers now offer PBT double-shot keycaps — combining PBT’s durability with double-shot’s long-lasting legends. Brands like Akko, Ducky, Vortex, and YMDK produce excellent PBT double-shot sets in the $30–60 range. This is the sweet spot for most keyboard enthusiasts.
Final Verdict
For most people, quality PBT keycaps (double-shot or dye-sub) at the $40–60 price point offer the best combination of feel, sound, and durability. They’ll outlast your keyboard and won’t develop the greasy shine that eventually affects ABS.
But if you want those beautiful retro colors or GMK’s legendary quality control, don’t let anyone tell you ABS is “bad.” Both materials have their place in the keyboard world.
