TPU Covestro 9380A

TPU Covestro 9380A is well‑balanced polyether‑based thermoplastic polyurethane elastomer. It is distinguished by excellent hydrolysis resistance, low‑temperature flexibility and anti‑microbial properties. It is particularly suitable for applications requiring sanitary protection or exposed to humid and low‑temperature environments, such as cable sheaths and hoses.

Main Applications

Wire & cable sheaths, hoses, corrugated tubes, robot‑arm cables.
