PTFE Gaskets Performance Advantages

   full name of PTFE gasket foreign also known as PTFE washers or Teflon (Teflon) washers by the Teflon rods, tubes, plates by mechanical turning or cutting of the flat washers, V-shaped Gasket, piston ring, ball valve washers, etc. with corrosion resistance, anti-aging and non-conductive and other good features.

At temperatures below -185 ° C. PTFE gasket gasket will become brittle. Pure PTFE gasket gasket is a clean seal product that does not contaminate any substance it touches and can be used in a wide range of food, pharmaceutical and other industries. What is polytetrafluoroethylene polytetrafluoroethylene (English abbreviation for Teflon or PTFE, F4), because the application is widely known as the "plastic king", the Chinese transliteration called "Teflon", "Teflon", " Teflon "," Teflon "," Teflon "and so on.

Polytetrafluoroethylene is made of polytetrafluoroethylene polymer compounds, with excellent chemical stability, corrosion resistance (is the world's best corrosion resistance of one of the materials, in addition to molten metal sodium and liquid fluoride outside , Can withstand all other chemicals, boiled in the water can not afford to change, widely used in various needs of anti-acid and alkali and organic solvent conditions), sealing, high lubrication non-stick, electrical insulation and good anti-aging , The temperature span of large (to + 250 ℃ to -180 ℃ temperature long-term work).

Polytetrafluoroethylene itself is not toxic to humans, but one of the raw materials used in the production process, perfluorooctanoate (PFOA), is thought to be carcinogenic. Its birth to solve the world of chemical, oil, pharmaceutical and other areas of many problems. It has been widely used as a sealing material and filling material.

Performance advantages: high temperature - the use of working temperature up to 250 ℃. Low temperature resistance - with good mechanical toughness; even if the temperature dropped to -196 ℃, can also maintain a 5% elongation. Corrosion resistance - for most chemicals and solvents, showing inert, strong acid and alkali resistance, water and a variety of organic solvents. Resistant to climate - the best aging life in plastics. High lubrication - the lowest coefficient of friction in solid materials. No adhesion - is the smallest surface tension in solid materials and does not adhere to any substance. Non-toxic - with physiological inertia, as artificial blood vessels and organs long-term implantation of the body without adverse reactions.

PTFE pad q ring as a sealing material has a variety of applications. Because of its high corrosion resistance, physical stability, high and low temperature resistance, the achievements of its good sealing performance, in the petroleum, chemical, pharmaceutical, power, steel industry has a wide range of applications. Suitable media include water, oil, acid solution, alkaline solution and almost all chemical components. American Othello Sealing Materials Group is the world's leading manufacturer of sealing materials, and now in the Chinese market can also see a lot of their products. Othello has a variety of products using polytetrafluoroethylene, and now to Othello products, for example, introduced polytetrafluoroethylene in the sealing material
