详细说明
Product Name: Made in China Acid and Alkali Resistant Polytetrafluoroethylene Rod Standard: Standard Shape: O-Ring Performance: Temperature Type: Stationary Seal Application: Car Material: PTFE Trademark: zhongrun Transport Package: Wooden Case Origin: Hebei China Product Description Polytetrafluoroethylene (Teflon or PTFE, F4) is widely known as the "King of Plastics" because of its wide application. Chinese transliteration is called "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon " and so on.Polytetrafluoroethylene (PTFE) is a polymer compound synthesized from tetrafluoroethylene. It has excellent chemical stability and corrosion resistance (it is one of the best corrosion-resistant materials in the world nowadays. It can resist all other chemicals except molten metal sodium and liquid fluorine. It boils in aqua regia unchanged and is widely used in various needs. It should be resistant to acid, alkali and organic solvents, sealability, high lubrication, non-stickiness, electrical insulation, good aging resistance, and long-term temperature span (can work at + 250 C to - 180 C).Polytetrafluoroethylene (PTFE) itself is not toxic to human beings, but ammonium perfluorooctanate (PFOA), one of the raw materials used in the production process, is considered to have carcinogenic effects.
