PTFEGasketThe English abbreviation isPTFE (commonly known as "plastic king"), brand name Teflon®.This material product has anti-acid resistanceAlkaliHigh temperature resistance, resistance to various
speciesorganic solventcharacteristics. It is widely used in the chemical and pharmaceutical industry and can be called the originator of the gasket industry.
1. PTFEIntroduction to Gasket
Soft PTFE refined. Durable, reliable sealing performance; PTFE itself has the best corrosion resistance and aging,
After special processing has a good resistanceCreepAnd cold flow resistance; can be used safely for a long time in a wide temperature range; Soft and easy to cut, can pass
Mechanical or manual cutting, easy to install.
2. PTFECharacteristics of the gasket
（1）Appearance color: white.
（2）Applicable temperature:-180 ℃-250 ℃
（3)Applicable medium:PH 0-14
（4）Pure plate：OTH-2100
（5）with corrosion resistance
（6）anti-aging
（7）Good characteristics such as non-conductive

3.PTFEThe importance of gaskets
（1）LikeThrust bearingAccept the axial force like that;
（2）Take out the heat generated like a radiator;
（3)In the case of high temperature and high pressure corrosion, static seal is now very difficult, but also in high-speed rotation, in a few millimeters of the sealing surface to complete the dynamic seal is even more difficult.

4.Auxiliary system of PTFE gasket
（1）Cut temperature rise, adhere to the end face outstanding smooth(Make all parts of PTFE gasket outstanding and work normally)
（2）In easily vaporized media) Insist that the pressure of the sealed cavity is higher than the full vapor pressure to prevent vaporization.
（3)Heat is heated in a cryopump.
（4）With regard to the crystallization of solid particles and the sealing of strong corrosive medium, the seal can be maintained without damage.
（5）Under better working conditions, the selection of auxiliary system will improve the stability and service life of the seal.(some sealing operation temperature, pressure, speed is not too high. No need for auxiliary body
Department can also work).
（6）The auxiliary system is part of the PTFE gasket..
5.Application of PTFE Gasket
TeflonSealing materialThere are many ways of application. Because of its high corrosion resistance, stable physical properties, high and low temperature resistance, it has achieved good sealing performance.
It is widely used in petroleum, chemical, pharmaceutical, electric power and steel industries. Applicable media include water, oil, acid solution, alkali solution and almost all chemical
Ingredients.
