Transform Your Typing Experience: A Detailed Guide to Keycap Materials and Textures
When you're building or upgrading your mechanical keyboard, keycaps might seem like a purely aesthetic choice. But the material and texture of your keycaps dramatically affect how your keyboard feels, sounds, and holds up over time.
As someone who's spent countless hours testing different keycap combinations, I've found that the right keycap material can transform a good keyboard into a great one. Let's break down everything you need to know about keycap materials and textures.
Common Keycap Materials
ABS (Acrylonitrile Butadiene Styrene)
ABS is the most common keycap material you'll encounter, and for good reason:
Cost-effective: Generally more affordable than other options
Versatile: Takes colors well, allowing for vibrant designs
Smooth feel: Typically has a slicker surface out of the box
The downside? ABS keycaps develop shine over time as oils from your fingers wear down the surface. This usually happens within a few months of regular use, depending on usage patterns.
Many stock keyboards come with thin ABS keycaps, but premium ABS options (like GMK sets) use thicker plastic with better durability.
PBT (Polybutylene Terephthalate)
PBT has become increasingly popular among keyboard enthusiasts:
Superior durability: Highly resistant to shine and wear
Textured finish: Usually has a slightly rougher, more textured feel
Thock sound profile: Produces a deeper, more satisfying sound when typing
Heat resistant: Won't warp easily under normal conditions
PBT keycaps typically cost more than basic ABS options but last significantly longer. If you're customizing your mechanical keyboard, PBT keycaps are often worth the investment for their longevity alone.
POM (Polyoxymethylene)
POM keycaps are less common but offer unique properties:
Smooth, almost slippery texture: Has a distinct feel that some typists love
Durable surface: Resistant to shine
Dense material: Creates a deeper sound profile
POM is sometimes called "Delrin" (a brand name) and has gained popularity for its unique typing feel. These keycaps are harder to find and typically more expensive.
PC (Polycarbonate)
PC keycaps are somewhat rare but offer interesting characteristics:
Translucent properties: Perfect for RGB lighting
Hard surface: Feels distinct from both ABS and PBT
Brittle: More prone to cracking if removed improperly
PC is often used for artisan keycaps or special accent keys rather than full sets.
Specialty and Hybrid Materials
Resin
Resin keycaps are typically used for artisan keycaps:
Highly customizable: Can be cast in countless designs
Variable texture: From glossy to matte depending on finish
Collectible: Often handmade and limited edition
Metal
Metal keycaps exist primarily as novelties or for specific keys:
Heavy: Provides significant weight
Cold to the touch: Distinct tactile experience
Durable: Extremely resistant to wear
Expensive: Significantly pricier than plastic options
Zinc, aluminum, and brass are the most common metals used.
Wood
Wooden keycaps offer a natural aesthetic:
Warm feel: Unlike the cool touch of plastics
Unique grain patterns: Each set is one-of-a-kind
Limited availability: Usually custom-made or specialty items
Keycap Textures and Finishes
The texture of your keycaps significantly impacts your typing experience. Here's what you'll encounter:
Smooth/Glossy
Feels slick under your fingers
Shows fingerprints more easily
Common on stock ABS keycaps
Tends to develop shine faster
Matte/Textured
Provides more grip for your fingertips
Hides fingerprints better
More resistant to visible shine
Common on PBT keycaps
Rough Texture
Maximum grip
Can feel abrasive to some users
Rarely shows shine
Found on some high-end PBT sets
Keycap Profiles and Their Impact on Feel
While not strictly about material, the profile of your keycaps dramatically affects how they feel:
Cherry profile: Lower, slightly angled keycaps popular in custom sets
OEM profile: The standard on many pre-built keyboards, slightly taller than Cherry
SA profile: Tall, spherical tops with a vintage feel
DSA profile: Uniform height with spherical tops
XDA profile: Uniform height with a slightly wider top surface
Each profile creates a different typing experience regardless of material. For a comprehensive look at different switch types that pair well with various keycap materials, check out our dedicated guide.
How Materials Affect Sound
Keycap material significantly impacts your keyboard's sound profile:
ABS: Generally produces a higher-pitched, "clackier" sound
PBT: Creates a lower-pitched, "thockier" sound due to its density
POM: Offers a unique deep sound that many enthusiasts seek

Durability Considerations
How long will your keycaps last? Here's a quick comparison:
ABS: Begins showing shine within 1-6 months of regular use
PBT: Can last years before showing significant wear
POM: Excellent shine resistance, similar to PBT
Resin/Metal: Extremely durable but can be impractical for regular typing
Maintenance Tips for Different Materials
To keep your keycaps looking and feeling their best:
ABS: Clean regularly with mild soap and water to remove oils
PBT: Can handle more aggressive cleaning if needed
Resin/Artisans: Avoid harsh chemicals that might damage finishes
Metal: Polish occasionally to maintain appearance
