TPU-CF10 | 10% Carbon Fiber Reinforced Thermoplastic Polyurethane
TPU-CF10 is a reinforced thermoplastic elastomer that combines the inherent flexibility, abrasion resistance, and chemical durability of Thermoplastic Polyurethane (TPU) with 10% short carbon fiber reinforcement. This elevated fiber content brings a notable increase in stiffness, dimensional stability, and load-bearing performance—while preserving TPU’s hallmark elasticity and resilience under repeated stress.
With the right balance of toughness and flexibility, TPU-CF10 is ideal for applications that operate in dynamic, high friction, and mechanically demanding environments. Whether it’s vibration-dampening mounts, wear-resistant bushings, or flexible protective structures, TPU-CF10 enables reliable, long-lasting performance across a wide range of industries.

Friction coefficient of PA12-LCF
The friction coefficient of TPU is typically between 0.3 and 0.5, while TPU-CF, with added carbon fiber, lowers the friction coefficient to between 0.2 and 0.4. The smaller the value, the better the wear resistance. Therefore, TPU-CF generally offers better wear resistance than pure TPU, especially under high-load conditions.
