The crystallinity of PTFE gray 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, strong acids and strong alkali, so it has the characteristics of the king of plastics. Good name.
Widely used in chemical industry, machinery, bridges, electric power, aviation, electronics and other fields, it is one of the most ideal engineering materials in modern industrial civilization.
