PTFE base tape film refers to a microporous film made of polytetrafluoroethylene as raw material, using special processing technology, and through calendering, extrusion, biaxial stretching and other methods.
Polytetrafluoroethylene, referred to as PTFE, also known as tetrafluoroethylene, is a non-polar linear crystalline polymer. It is a white, odorless, tasteless and non-toxic powder. The concentrated dispersion is milky white. Milky liquid.
The crystallinity of its PTFE base film products is 55%~75%. When the temperature is greater than 327°C, the crystallization disappears and the product is completely transparent.
Because in the molecular structure of PTFE, the carbon atoms are surrounded by 4 fluorine atoms, it has a very high chemical stability and can withstand the erosion of many corrosive media, such as strong acids, strong bases, strong oxidants, grease, Ketones, ethers, alcohols, etc. have no effect on it even at high temperatures, so it has the reputation of the King of Plastics.
? is a fluorine material film manufacturer integrating production, sales and customization.
Our company is different from other manufacturers. Our company can produce products according to user requirements.
The key to the technology is the optimized combination of speed ratio, pressure ratio, operating temperature and other parameters. According to the ratio and pore-forming medium, the air permeability, thickness and void ratio can be adjusted online to meet your different requirements. .
