Friction coefficient of TPU-CF
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.
