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:

  1. ABS: Generally produces a higher-pitched, "clackier" sound
  2. PBT: Creates a lower-pitched, "thockier" sound due to its density
  3. 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
