Polycaprolactone TPU Resin | Low-Temperature Flexible TPU for Winter Footwear, Cables, Industrial Parts
Polycaprolactone TPU Resin (PCL TPU) – Overview & Applications
Low-temperature flexible TPU for winter footwear, cold-climate cables, hoses and industrial parts.
Chemdo polycaprolactone-based TPU (PCL TPU) combines excellent low-temperature flexibility,
hydrolysis resistance, abrasion resistance and mechanical strength.
It is particularly suitable for applications that must stay flexible and durable in cold or wet environments,
such as winter footwear components, cold-climate cables and hoses, and outdoor industrial parts.
