TPU Wanhua Chemical WHT‑8185
TPU Wanhua Chemical WHT‑8185
TPU Wanhua Chemical WHT‑8185 is polyether‑based TPU optimized for extrusion processing with outstanding low‑temperature resistance. Its standout feature is the low‑temperature flexibility temperature of ‑69℃, making it ideal for pipes and cables that need to retain flexibility under cold‑climate conditions.
Main Applications
Low‑temperature resistant tubing, wire & cable sheaths, special‑shaped profiles.
