Analyzing the product characteristics of PET silicone-free release film. Silicone-free release film is made from high-flatness and high-cleanliness polyester film as the substrate, with thicknesses ranging from 12μ to 188μ for transparent substrates and 12μ to 100μ for matte substrates. Coated with imported silicone-free release agent and developed based on years of practical experience, it has become a top-tier silicone-free release film in the market. Now let's explore the product characteristics of PET silicone-free release film.
1. The product components are 100% free of silicone residue, with stable release effect and are environmentally friendly.

II. Release film is a high-end laminating insulation material with extremely high filling capability, capable of completely replacing copper foil and PTX laminating plates. Matte release film is the preferred choice for the processing of printed circuit boards made of epoxy resin. As an insulation material, it possesses high tensile strength and tear resistance, low shrinkage rate, and high anti-adhesion properties.
III. The surface is clean and scratch-free, with uniform coating, no transfer, and low shrinkage.
Product Application: Silicone-free release film, used in the manufacturing of FPC/PCB/HDI/LCL/laminated and stacked circuit boards. The surface adopts a silicone-free coating process, eliminating the issue of silicone oil residue pollution. Silicone-free release film is a high-quality, eco-friendly product provided to customers to meet this demanding process.
