Quick Answer

Choose ABS HyperX Pudding Keycaps if you prefer a smoother, slightly softer feel and don't mind eventual shine from wear. Pick PBT keycaps if you want a textured, matte finish that resists shine and lasts longer. Both fit most mechanical keyboards, but your typing preference and durability needs will decide the winner.

ABS vs PBT: What's the Difference?

ABS (Acrylonitrile Butadiene Styrene) is the most common keycap material. It's softer, which gives a smooth, slightly silky feel under your fingers. The trade-off is that ABS keycaps can develop a glossy shine over time from natural oil and friction. HyperX Pudding Keycaps in ABS use a translucent dual-layer design and signature HyperX font to maximize RGB lighting effects.

PBT (Polybutylene Terephthalate) is a harder, more durable plastic. It has a textured, matte finish that resists shine and feels grippier. PBT keycaps are less common in stock keyboards because they cost more to produce. If you want a consistent, non-glossy surface for years, PBT is the better choice.

How Material Affects Sound and Feel

ABS keycaps tend to produce a slightly higher-pitched, snappier sound when typing. The softer plastic absorbs less vibration, so each keystroke feels a bit more direct. PBT keycaps, being denser, often produce a deeper, thockier sound and a more muted bottom-out feel. Neither is objectively better—your preference depends on whether you like a crisp or a cushioned response.

If you are sensitive to keycap texture, PBT's grain may feel too rough for long sessions. ABS's smooth surface can feel more comfortable for some typists, but it will eventually polish to a shine in high-use areas like the WASD cluster or spacebar.

Durability and Longevity

PBT keycaps are significantly more resistant to wear. They will not develop a shiny appearance from normal use, and they resist fading from UV light better. ABS keycaps, while still durable, will show signs of use over months or years. For a keyboard you plan to keep for a long time, PBT offers better long-term value.

However, ABS keycaps are not fragile. They can last for years without cracking or breaking. The shine is cosmetic, not structural. If you change keycaps frequently or enjoy the look of a worn-in set, ABS may be perfectly fine.

Compatibility and Installation

Both ABS and PBT HyperX Pudding Keycaps are full key sets compatible with HyperX and most other mechanical gaming keyboards. They use standard Cherry MX-style stems. The set includes a stylish HyperX keycap removal tool for easy installation. No matter which material you choose, installation is the same simple process.

Decision Rules: ABS vs PBT

  • Feel Preference: ABS is smooth and slightly silky. PBT is textured and matte. Choose ABS for a soft touch; choose PBT for a grippy, textured feel.
  • Shine Resistance: ABS will develop a glossy shine over time from use. PBT resists shine indefinitely. If you want a consistent matte look, go with PBT.
  • RGB Lighting: Both materials use a translucent dual-layer design for excellent light diffusion. Material does not affect brightness. RGB performance is identical; your choice depends on feel and durability.

Product Facts

  • HyperX Pudding Keycaps - ABS: HyperX Pudding Keycaps feature a translucent dual-layer style and our signature HyperX font, both of which are designed to provide extra brilliance. These ABS keycaps provide a different feel than our keycaps made of PBT material. The dual-layer design maximizes RGB lighting, and the ABS material gives a smooth, responsive feel. If you want vibrant light diffusion and a softer touch, this set is a great fit.
  • HyperX Wrist Rest - Keyboard - Tenkeyless: The HyperX Wrist Rest provides comfortable wrist cushioning for use with a mouse or a variety of keyboard sizes. It has an anti-slip natural rubber underside crafted to remain stable while your fingers fly across the keys. Pairing your new keycaps with a wrist rest reduces strain during long typing or gaming sessions. The anti-slip base keeps it steady, so you can focus on your keystrokes.

Which Should You Choose?

Best for

  • Gamers who prefer a smooth, responsive key feel and plan to replace keycaps within a year or two
  • Typists who want the most vibrant RGB lighting and don't mind eventual cosmetic wear

Not for

  • Users who want a matte, non-shiny keycap surface for years of heavy use
  • Those who prioritize maximum durability and resistance to wear over initial feel
