Part Number HM426, Film-PTFE High-Modulus Backing Substrates


PTFE films provide a conformable release surface and exhibit a remarkably low coefficient of friction and non-stick properties. PTFE films have high temperature resistance and are virtually unaffected by all chemicals. At elevated temperatures, PTFE film still retains excellent tensile strength. Service temperatures range from -100°F to +500°F (-73°F to +260°C). Film applications include high temperature coil and capacitor wrapping, composite bonding, masking, and conveyor release linings.
