TPV Celanese 201-73
TPV Celanese 201‑73（塞拉尼斯）
TPV Celanese 201‑73 is a medium‑hardness, well‑balanced and easy‑to‑process thermoplastic vulcanizate. Its core advantages include good elasticity, weather resistance, broad chemical resistance (except certain oils and solvents), and recyclability.
Main Applications
Automotive Industry: Seals, glass run channels, bumpers, cooling pipes and hoses. Compared with conventional EPDM rubber, it enables lightweight design and simplified processing. Consumer & Industrial Goods: Power‑tool components, gaskets, pipes and sealing parts requiring flexibility and sealing performance. Others: Wire and cable sheaths.
