ptfe base tape film, also known as polytetrafluoroethylene tape film, is currently the most widely used in modern industrial production One of the engineering materials.
The relative molecular weight of polytetrafluoroethylene is relatively large, ranging from hundreds of thousands to tens of millions, usually several million (the degree of polymerization is around 104, while polyethylene is only around 103). The general crystallinity is 90-95%, and the melting point is 327-342°C. The CF2 units in the polytetrafluoroethylene molecule are arranged in a zigzag shape. Since the radius of fluorine atoms is slightly larger than that of hydrogen, adjacent CF2 units cannot be completely trans-cross-oriented, but form helical twisted chains that are almost covered by fluorine atoms.
PTFE base film is a microporous film made by special processing technology, such as calendering, extrusion, and biaxial stretching. This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties. The porosity can reach 80%~90%, and after high-temperature heat setting treatment, the microporous structure is stable and can effectively intercept dust particles. Moreover, its pore size is small and uniform, and its surface filtration mechanism makes it easy to remove dust. It has strong hydrophobicity and low surface energy. , has good non-adhesive ability, effectively removes dust accumulated on the surface, and can restore performance by washing with water or backflushing, greatly extending the service life, and the filtration efficiency can reach 99.999995%.
The ptfe base tape film produced by the manufacturer uses imported raw materials, has a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop, ensuring the production quality of ptfe film ;Using production and testing instruments imported from the United States to test the quality of PTFE film, and passing international SGS testing and certification, as well as ISI testing and certification.
