XIFLON ETFE FILMS is a semi-finished product manufactured from high-performance ethylene tetrafluoroethylene (ETFE) resin, sourced from carefully selected and trusted suppliers including XIFLON fluoropolymer resin.
Inert to most chemicals; excellent weathering, UV and radiation resistance.
Performs from −150 °C to +165 °C, with peaks up to 220 °C.
Strong insulation; dielectric strength 5,500 V/mil at typical thickness.
Low-stick, dirt-resistant surface; high contact angle 98° for cleanability.
Our ETFE films are produced by melt-extrusion casting of high-purity ETFE resin under strict control.
This ensures smooth, weather-resistant surfaces, stable thickness, and reliable chemical, thermal, and electrical performance for long-term outdoor use.
Uniform thickness and width for precise, stable fit.
Smooth, defect-free finish that preserves clarity.
Maintains mechanical strength and chemical resistance.
Lots verified to ASTM/UL methods for reliability.
