How much do you know about high temperature resistant plastic film?
xinst5月 30, 2020
High temperature resistant film is a kind of plastic film. As the name implies, the biggest feature of this type of film is its high heat resistance. The traditional definition refers to the high temperature resistant film with a temperature resistance of more than 200oC, and according to the heat resistance level of the thin film insulating material, the long-term working temperature of H level above 180oC can be called a high temperature resistant film.
Teflon film, also known as Teflon film, is a polymer obtained by polymerizing tetrafluoroethylene as a monomer. White waxy, translucent, excellent heat resistance, cold resistance, density about 2.2 g / ml, can be used for a long time at -180 ~ 260oC. This material has the characteristics of acid resistance, alkali resistance, and resistance to various organic solvents, and is almost insoluble in all solvents. PTFE has a very low coefficient of friction, so it can be used for lubrication.
The processing technology of PTFE film is complicated, it is made of suspended polytetrafluoroethylene resin by molding, sintering, cooling into a blank, and then turning and rolling. . Non-oriented film calendering is 1.1-1.8 times as semi-oriented film. PTFE film is used for capacitor dielectric, as wire insulation, electrical instrument insulation, and dense gasket. Due to PTFE plastic film ...
