Introduction to polytetrafluoroethylene products

    Polytetrafluoroethylene (PTFE, TEFLON), also called king of plasticsis, is a kind of the most excellent plastics

    Main properties:

• High- and low-temperature resistance: it can be used safely in environment with temperatures ranging from -180°C to +260°C
• Resistance to atmospheric aging and radiation: it has excellent resistance of weathering, resistance to fire, with high oxygen index, without water absorption. It also has good resistance to radiation. When exposed in atmosphere, its properties will not degrade.
• Insulatibity and corrosion resistance: it has excellent dielectric propertics, with resistance to high voltage. It has corrosion resistance, and cannot be dissolved in any kind of chemical solvent. It remain constant in aqua regia, sodium hydroxide, uranium fluoride, etc.
• Resistance to wear: It has good wear resistance, and has the smallest coefficient of static friction among plastics, with good self lubricating property, and excellent surface inadhesion. It¡¯s tensile strength is very strong.

    Nowadays, with the development of science & technology, and improvement of people¡¯s living condition, polytetrafluoroethylene products have got more and more applications in every aspects of our society, ranging from national security industry to other commercial industry. It can be used in aeronautics and astronautics, instrument and meter, telecommunication, petrochemical industry, metallurgy, electric power industry, railway and transportation, electrical machines, household appliances, tall building, lamps, etc.
