When it comes to creating the ultimate keyboard experience, the choice of keycap material plays a decisive role in both long-term satisfaction and tactile feel. PBT keycaps outperform ABS with a crushing advantage thanks to their robust material nature—even in recycled form, rPBT remains impressively durable.

Imagine PBT’s molecular structure as a tightly packed Lego wall, whereas ABS resembles loosely stacked blocks. This high crystallinity and density give PBT a naturally textured, anti-slip surface. No matter how intense your typing, PBT resists deformation. In contrast, ABS keycaps begin to look shiny and greasy within months, not due to a lack of effort but because their soft molecular chains are polished by friction and finger oils.
The rubber phase in ABS may offer initial flexibility, but it also makes the molecular structure prone to plastic deformation and aging under repeated stress—this is the root cause of the infamous “keycap shine.”
And what about after recycling? Recycled PBT (rPBT) holds its ground. Despite a slight loss in toughness, it retains its core strengths: wear and oil resistance. Recycled ABS, on the other hand, deteriorates much faster.
Heat? Bring it on: Reinforced PBT withstands over 200°C before deforming. Gaming on a hot summer day? No problem. ABS? It softens at just 60°C—imagine your WASD keys collapsing mid-tournament!
Chemicals? No worries: PBT laughs at sweat, oils, and cleaners. It resists aging, yellowing, and degradation, even after extended use. Well-made rPBT retains much of this stability, ensuring that keycap colors stay vibrant and saturated over time.
Think recycled materials are second-rate? rPBT proves otherwise. With glass fiber reinforcement, halogen-free flame retardancy, and PC/PET alloy blending, rPBT becomes a performance powerhouse. Used in automotive battery brackets and industrial gears—keyboard keycaps are light work in comparison.
rPBT keycaps might cost 30% more than rABS, but think long-term: ABS wears out in 6 months, while PBT stays strong for 5+ years. With big brands like ROG and Dareu adopting rPBT and even offering five-sided dye sublimation—performance meets style!
Choosing rPBT is like hiring a Swiss Army knife for your keyboard: durable, reliable, and eco-conscious. With oil resistance, abrasion resistance, color retention, and thermal stability, rPBT keycaps offer both physical resilience and lasting confidence—clearly outshining rABS in every aspect.
