TPV Celanese 111‑35
TPV Celanese 111‑35（塞拉尼斯）
TPV Celanese 111‑35 is a soft, low‑hardness thermoplastic vulcanizate with high elasticity. Its core advantages include good elasticity, weather resistance, chemical resistance (except certain oils and solvents), and recyclability.
Main Applications
Automotive Industry: Sealing strips, gaskets, dust boots. Enables lightweight design and simplified processing compared with conventional EPDM rubber. Consumer & Industrial Goods: Soft‑touch handles, pipes, household‑appliance sealing parts and various flexible gaskets & seals. Others: Printer components, sports‑goods parts.
