CHR 2255 PTFE films provide a conformable release surface and exhibit a remarkably low coefficient of friction and non-stick properties. Has a dielectric strength of 15000V. PTFE films have high temperature resistance and are virtually unaffected by all chemicals. - CHR 2255 is manufactured from modified high-modulus PTFE film coated with high temperature silicone adhesive. Has a tensile strength of 60 lb/Inch. At elevated temperatures, PTFE film still retains excellent tensile strength.
