Release film features and uses:

　　1. No migration phenomenon, eliminating silicone resinThe danger of transferring the release membrane to the material it adheres to;

　　2 The tolerance for weight per unit area of single or double sided coating of release film is very small;

　　3. The base film has excellent mechanical strength and chemical properties;

　　4. It has high stability under extreme weather conditions, with a high temperature resistance of around 130 ℃ over a long period of time and around 180 ℃ within one hour;

　　5. Long shelf life;

6. Adhesive based release PET can be divided into light release type, medium release type, and heavy release type based on the mobility of silicon and the changes in release force after heating. It can control the release force according to requirements and has good heat resistance. The release film has different thicknesses for customers to choose from, and the general application thickness is 12UM/19UM//25UM/30UM/36/UM/38UM/50UM/75UM/100UM. The product can be divided into light, medium, and heavy release, and different release forces are suitable for sticking different adhesive tapes or films.

Characteristics and Applications of Release film

　　Due to its superior high-temperature resistance, it is mainly used in FPC is the substrate, which is uniformly coated with an extremely thin release agent on one or both sides,The surface of the release film is flat and smooth, evenly coated, without defects such as wrinkles, particles, bubbles, and pinholes. The product has excellent physical properties, small thickness tolerance, and low heat shrinkage rate. It is mainly the selected isolation material for processing epoxy resin printed circuit boards, with high tensile strength and tear strength.

　　PET Release film is generally used to isolate viscous materials, widely used in electronicsMobile phone, adhesive, printed circuit board and other industries, including packaging, printing, silk screen printing, pad printing, nameplate, thin film switch, flexible circuit, insulation products, circuit board, laser anti-counterfeiting, bonding, electronics, sealing material film, reflective materials, waterproof materials, medicine (plaster paper), sanitary paper, adhesive products, die cutting and punching processing, etc., are suitable for heat transfer printing and are more suitable for die cutting gaskets Adhesive products stamping, etc. Controllable release force, high glossiness, high cleanliness, residual adhesion of 94%, and good surface performance.
