0.12 N/50mm Release Force After 70°C Aging and 95% Residual Adhesion from a PET Silicone Release Film Factory and Supplier
Product Overview
Some release processes involve heat. When a silicone release film is expected to hold its release force after 70°C aging, the coating and cure have to be right — not just the base film. This 30μm PET Silicone Release Film is a light-release silicone-coated polyester film built for molding, lamination, and protective film processes where heat exposure is part of the routine. It delivers a 31B release strength of 0.07 N/50mm at room temperature and 0.12 N/50mm after 70°C aging, with a residual adhesion ratio of 95%. Those numbers only stay stable in volume production when the PET Silicone Release Film Manufacturer controls silicone coating weight and cure consistency tightly.
