ETFE EF is made of ETFE (ethylene-tetrafluoroethylene copolymer) resin through melt extrusion. The release film used for molding processin the LED/IC industry has excellent release properties, flexibility, and high temperature resistance (long-term 165°C).

Benefits

· Excellent non-stick and release performance

· Excellent mechanical properties

· Superior elongation and formability

· Excellent flexibility

· Excellent temperature resistance, long-term 165°C

· Can be single-sided or double-sided matte
