PET high temperature resistant protective film has good chemical properties

The commonly used protective film for PET high temperature resistant protective film is PET protective film, because it has good electrical, thermal and chemical properties. In the welding operation, the protective film can withstand the temperature of the welding operation. This protective film is also used for wire insulation, transformer and engine insulation.

The main reason why PET high temperature resistant protective film is widely used is that it can accept the heat of manual and automatic soldering. PET protective film has excellent heat resistance and can be used continuously at temperatures close to 300°C. At these temperatures, copper boxes and solder joints will be quickly destroyed due to oxidation and internal metal proliferation. The performance of the laminate depends on the adhesive properties of the adhesive and the supporting protective film. Therefore, it is very important to eliminate the influence of adhesives and protective films when choosing laminates.

The polyimide protective film has excellent heat resistance and can be used continuously at temperatures close to 300°C. At these temperatures, copper boxes and solder joints will be quickly destroyed due to oxidation and internal metal proliferation. The performance of the laminate depends on the adhesive properties of the adhesive and the supporting protective film. Therefore, it is very important to eliminate the influence of adhesives and protective films when choosing laminates.

PET double-sided protective film is flame retardant. When bonded with a special composite refractory adhesive, the laminate can withstand high temperatures. However, many flexible printed circuit adhesives have lower impedance. Although they can accept soldering temperatures, these adhesives have poor adhesion properties in PET heat-resistant protective film laminates.
