Determinants of PET plastic film quality and its application range
May 29, 2019
PET plastic film is used a lot, it is a kind of release material commonly used in the industries of adhesive, electronics, die cutting, printing, etc. The factors affecting PET plastic film include substrate, residual adhesion rate, peeling force, processing environment and so on. The PET plastic film is coated on the surface layer of the PET film, and the quality of the substrate directly affects its performance.
The residual adhesion rate of the PET plastic film refers to the force of the release paper after the first peeling and the second peeling. The calculated data mainly reflects the curing effect of the silicone oil. The size of the peel force directly affects the performance of the PET plastic film. The general industry standard peel force tolerance range is ±15%. With the advancement of various products and the improvement of quality technology, the cleanliness requirements for PET plastic films are becoming more and more strict, especially in the electronic film cutting industry.
The different functions of PET plastic film are also constantly improving. It can be applied to the printing of printed circuit boards, electronic parts, fixing of resistive capacitors during the production and PCB board impregnation process, shielding the gold finger department and preventing the immersion and contamination of the plating solution, and the gold plating of the printed circuit board. For protection. And home appliances, machinery, electronics and other industries need high-temperature paint spray protection, to play a high-temperature binding, and can also be used in the release paper joint.www.xmlfilm.com
