PTFE Gaskets High Temperature

High temperature - use operating 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 the solid material and does not adhere to any substance. Non-toxic - with physiological inertia, as artificial blood vessels and organs long-term implantation in the body without adverse reactions.

At temperatures below -185 ° C. PTFE gasket gasket will become brittle. Pure PTFE washers are a clean sealed product that does not contaminate any substance that is exposed to it and can be used in a wide range of industries such as food and medicine. 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, boil 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 , Temperature span (can be in the temperature of + 250 ℃ to -180 ℃ long-term work).

Polytetrafluoroethylene itself is not toxic to humans, but ammonium perfluorooctanoate (PFOA), one of the raw materials used in the production process, is thought to have carcinogenic effects. 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.

It is made of rubber ring and metal ring as a whole, and is used to seal the sealing ring of thread and flange connection. The ring includes a metal ring and a rubber gasket. Metal ring rust treatment, rubber ring generally use oil nitrile rubber or fluorine rubber. Combination pad with metric and imperial sizes, with standard JB982-77 combination of metal pad and rubber combination of the form. Combination sealing gasket for threaded pipe fittings and plug seal, it is generally used with the card-type pipe joints, used to block the mouth, mainly for hydraulic valve pipe fittings threaded connection of the end of the static seal, applicable to the United Kingdom, the United States Inch thread and the French, German standard metric threaded connection of the end of the static seal. Combination sealing gasket according to the structure can be divided into A-type, B-type; according to the different packages can be divided into all-inclusive,
