Introduction
When choosing keycaps, many people assume that PBT is always better because it resists shine and yellowing. In reality, keycap material also affects RGB lighting, sound, texture, durability, and design possibilities. The right choice depends on how you use your keyboard.
PBT and ABS: What Is the Difference?
ABS keycaps usually have a smoother surface and produce a cleaner, slightly higher-pitched sound. Their excellent color clarity also makes ABS and ABS-PC combinations popular for transparent or RGB-focused designs.
However, ABS is more likely to develop a glossy surface after extended use and generally has lower heat resistance than PBT.
PBT keycaps usually feel more textured and often create a deeper typing sound. They are more resistant to surface shine, fading, and heat deformation, making them well suited to long-term everyday use. However, keycap thickness, profile, switches, and keyboard construction can influence sound more than the material alone.
Which Material Is Better for RGB?
ABS and PC-based keycaps are often preferred for bright RGB setups because light can travel through them more easily. Transparent shells and pudding-style designs can create a stronger glow around each key.
PBT can also support shine-through legends when combined with double-shot construction, although the lighting may appear softer or less transparent than clear ABS or PC keycaps.
Understanding Keycap Manufacturing
Side-Printed Legends
Side-printed legends are placed on the front face of each keycap. This creates a clean, minimalist appearance from above and works especially well with south-facing RGB keyboards.
Double-Shot Molding
Double-shot keycaps are made from two separately molded plastic layers. Because the legends are part of the keycap instead of being printed on its surface, they are highly resistant to fading.
Both ABS and PBT can use double-shot construction.
Five-Sided Dye Sublimation
Dye sublimation uses heat to transfer ink into the keycap surface. Five-sided dye sublimation extends the design across the top and four sides, making it ideal for detailed themes and colorful artwork.
This process is most commonly used with light-colored PBT. It usually does not create shine-through legends.
Is PBT Always Better?
Not necessarily. Choose PBT if you prefer a textured surface, better resistance to shine, and long-term durability. It is ideal for office work, frequent typing, and understated keyboard builds.
Choose ABS or an ABS-PC combination if you want stronger RGB diffusion, transparent effects, vivid colors, or a smoother touch. It can be a better choice for decorative and lighting-focused setups.
The best keycap is the one that matches your preferred appearance, sound, texture, and keyboard layout.

Conclusion
PBT and ABS each offer different advantages. PBT focuses on texture, durability, and resistance to shine, while ABS and PC-based designs often provide brighter lighting and more transparent effects. Instead of choosing by material name alone, consider how the keycaps will look, sound, and feel on your keyboard.
