Teflon flat pad
- product description
The English abbreviation of PTFE gasket is PTFE, which has the characteristics of acid and alkali resistance, high temperature resistance, and resistance to various organic solvents. It is widely used in the chemical and pharmaceutical industry. Because of its high corrosion resistance, stable physical properties, and high and low temperature resistance, it has achieved its good sealing performance. It is widely used in the petroleum, chemical, pharmaceutical, power, and steel industries. Suitable mediums include water, oil, acid solution, alkali solution and almost all chemical components.
Polytetrafluoroethylene is a polymer compound formed by the polymerization of tetrafluoroethylene. It has excellent chemical stability and corrosion resistance (it is one of the best corrosion resistance materials in the world today, except for molten metal sodium and liquid fluorine. Resistant to all other chemicals, it does not change when boiled in aqua regia, and is widely used in various working conditions that require resistance to acids and alkalis and organic solvents), tightness, high lubricity and non-stickiness, electrical insulation and good aging resistance 2. Large temperature resistance span (can work for a long time under the temperature of + 250 ℃ to -180 ℃).
High temperature resistance-use working temperature up to 250 ° C.
Low temperature resistance-with good mechanical toughness; even if the temperature drops to -196 ℃, it can maintain 5% elongation.
Corrosion resistance-For most chemicals and solvents, it is inert, resistant to strong acids and bases, water and various organic solvents.
Weather resistance-has the best aging life among plastics.
High lubrication-the lowest coefficient of friction in solid materials.
Non-adhesion-is the smallest surface tension in solid materials and does not adhere to anything.
Non-toxic-It is physiologically inert, and has no adverse effects as long as it is implanted into the body as a prosthetic blood vessel and organ.
