Introduction
There are two types of keycaps: ABS (Acrylonitrile Butadiene Styrene) and PBT (Polybutylene Terephthalate). Imagine a world where every keystroke tells a story. In this realm, ABS and PBT keycaps are the unsung heroes, shaping not just the tactile feedback but also the sound. This guide will walk through the differences of ABS and PBT, exploring their durability, texture, and sound.
Durability
When it comes to durability, PBT keycaps are generally considered superior. PBT keycaps are more resistant to wear, solvents, and heat, ensuring that they don't develop a shiny finish over time as quickly as ABS keycaps do. A study conducted by the Keyboard Company shows that PBT keycaps can withstand over 50 million keystrokes, significantly more than the 30 to 40 million keystrokes ABS keycaps can endure.
Data Point:
- PBT Keycaps: Over 50 million keystrokes (Keyboard Company)
- ABS Keycaps: 30-40 million keystrokes
This increased durability makes PBT keycaps a favorite among heavy users and enthusiasts who value longevity and consistency in their typing experience as well as people who want to spend more for custom sets that last a long time.
Texture
Texture is a subjective aspect but plays a crucial role in the user's typing experience. ABS keycaps are known for their smooth, slightly glossy finish. This can be appealing initially, but they can develop a greasy shine over time due to wear and the oils from your fingers. In contrast, PBT keycaps offer a more textured, matte finish which not only provides a more consistent feel over time but also offers better grip, as noted by a comparative study on keycap materials by WASD Keyboards.
User Experience Reports:
- ABS Keycaps: Smooth, glossy finish, prone to shine over time.
- PBT Keycaps: Textured, matte finish, offers better grip.
Sound
ABS keycaps generally produce a lower-pitched, thockier sound, which can be perceived as softer or less intrusive. PBT keycaps, due to their thicker and denser material, tend to produce a higher-pitched, more solid sound, as documented in the mechanical keyboard community forums. This can be particularly satisfying for typists who enjoy a more pronounced auditory feedback. This will of course be impacted by several other factors such as switch choice, board housing, and sound dampening materials.
Community Feedback:
- ABS Keycaps: Lower-pitched, softer sound.
- PBT Keycaps: Higher-pitched, more solid sound.
Conclusion
In the end, the choice between ABS and PBT keycaps boils down to personal preference and priorities. If you value longevity and a consistent texture, PBT might be your material of choice. On the other hand, if you prefer a softer sound and a smoother initial feel, ABS could be more to your liking.
