0.07 N/50mm Release Force and 95% Residual Adhesion from a PET Silicone Release Film Factory and Supplier
Product Overview
A silicone release film lives or dies by its coating. At 19μm, the silicone layer has to be uniform, fully cured, and stable through heat aging — otherwise the film blocks, tears, or releases unevenly. This 19μm PET Silicone Release Film is a light-release silicone-coated polyester film built for precision molding, lamination, and protective film processes. 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 values only hold in volume production when the PET Silicone Release Film Manufacturer controls silicone coating weight and cure consistency tightly.
Technical Characteristics
The following values are representative measured data for the 19μm specification. They are not guaranteed values.
- Base film thickness: 19 μm

Key Properties
- Light and stable silicone release force at room temperature and after heat aging
- High residual adhesion ratio of 95%
- Consistent silicone coating wettability for mold release surfaces
- 19μm base film with better handling than ultra-thin silicone films
Applications
19μm PET Silicone Release Film is used as a mold release film, carrier film, and protective film in composite molding, adhesive processing, electronics lamination, and general industrial release applications. It suits roll-to-roll and sheet-based production where a thin but manageable silicone release film is required.
