The Plastic King

Teflon tube manufacturers take you to understand Teflon, Teflon is also known as polytetrafluoroethylene. It has good heat resistance and weather resistance. The relative molecular mass of polytetrafluoroethylene is relatively large, ranging from hundreds of thousands to over 10 million, generally to millions (the degree of polymerization is on the order of 104, while polyethylene is only 103). Generally, the crystallinity is 90 ~ 95% and the melting temperature is 327~342 ℃. The CF2 units in the polytetrafluoroethylene molecule are arranged in a sawtooth shape. Since the radius of the fluorine atom is slightly larger than that of the hydrogen, the adjacent CF2 units cannot be completely oriented in a trans-cross direction, but form a spiral twisted chain. The fluorine atoms almost cover the surface of the entire polymer chain. This molecular structure explains the various properties of polytetrafluoroethylene. When the temperature is lower than 19 ℃, a 13/6 helix is formed; a phase transition occurs at 19 ℃, and the molecules are slightly unwound to form a 15/7 helix. What a great.
