Introduction to the common characteristics and uses of PET release film

1. No transfer situation, avoiding the danger of silicon release film transferring to its surrounding original data;

2. The utilization coefficient component error value of the single-layer or double-layer coating of the release film is not significant;

3. The wall reinforcement has excellent impact toughness and chemical properties;

4. In extreme environments, the temperature reliability is high, and the heat resistance time can reach 130 ℃ in just over an hour, reaching around 180 ℃;

5. Long shelf life;

6. The mobility and peeling force of PET heated silicon for adhesive release are divided into light release types Intermediate detachment type Peel strength can be adjusted according to requirements, and it has good temperature resistance.

Customers should choose different thicknesses of release films. Generally used thickness: 12UM/19UM//25UM/30UM/36/UM/38UM/50UM/75UM/100UM The project is light In the middle Different types of peel strength are suitable for bonding belts or plastic films with different viscosities.

Characteristics and main uses of release film

Single layer Due to its excellent heat resistance, double-sided release film is mainly used for FPC boards. A thin layer of release agent is evenly coated on one or both sides, and the surface of the release film is bright and shiny, with a uniform coating and no wrinkles Particulate matter Bubble. Disadvantages such as small holes, excellent product process performance, small thickness, low thermal shrinkage rate, usually used as protective raw materials in the processing of epoxy resin printed circuit boards, with high tensile strength and tear strength.

PET isolation film is generally used to protect adhesive materials and is widely used in electronic devices, mobile phones, and adhesives Printed circuit board and other categories, outer packaging Packaging printing. Screen printing ink Transfer printing Screen printing equipment Thin film buttons Soft roads Insulation layer products Circuit board. Laser anti-counterfeiting Catering to electronic device. Use membrane rubber seals Reflective material Waterproof coating. Pharmaceutical industry (ointment paper) Environmental hygiene paper Plastic industry Suitable for areas such as heat transfer printing technology, more suitable for film cutting gaskets Adhesive product punching, etc. Controllability of peel strength High smoothness High cleanliness level Residual adhesion force of 94%, high cost-effectiveness on the surface.
