Advantages of Ptfe plastic pull ring

Polytetrafluoroethylene [PTFE, F4] is one of the best corrosion-resistant materials in the world today, so it is known as the "King of Plastics". It can be used for a long time in any kind of chemical medium. Polytetrafluoroethylene seals, gaskets, and gaskets. Polytetrafluoroethylene seals, gaskets, and sealing gaskets are made of suspended polymerized polytetrafluoroethylene resin molding. Compared with other plastics, polytetrafluoroethylene has excellent chemical corrosion resistance and temperature resistance. It has been widely used as a sealing material and filling material.
High temperature resistance - the working temperature is up to 250℃. Low temperature resistance - has good mechanical toughness; even if the temperature drops to -196℃, it can maintain an elongation of 5%. Corrosion resistance - inert to most chemicals and solvents, resistant to strong acids and alkalis, water and various organic solvents. Weather resistance - has the best aging life among plastics. High lubricity - has the lowest friction coefficient among solid materials. Non-adhesion - has the smallest surface tension among solid materials and does not adhere to any substance. Non-toxic - physiologically inert, no adverse reactions when implanted in the body as artificial blood vessels and organs for a long time. The relative molecular mass of polytetrafluoroethylene is relatively large, ranging from hundreds of thousands to more than 10 million, and generally millions (the degree of polymerization is in the order of 104, while polyethylene is only in the order of 103)
