Polytetrafluoroethylene is a polymer compound formed by 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, boiling in aqua regia will not change, widely used in various working conditions that require resistance to acid, alkali and organic solvents), sealing, high lubricating non-stick, electrical insulation and good anti-aging properties , Large temperature span (can work for a long time at the temperature of +250℃ to -180℃)
PTFE performance advantages
High temperature resistance: the working temperature is up to 250℃.
Low temperature resistance: good mechanical toughness; 5% elongation can be maintained even if the temperature drops
to -196℃.
Corrosion resistance: It is inert to most chemicals and solvents, resistant to strong acids and alkalis, aqua regia
and various organic solvents.
Weather Resistant: Has the best aging life of any plastic.
High Lubrication: It is the lowest friction coefficient among solid materials.
Non-stick: It is the smallest surface tension in solid materials and does not stick to anything.
Non-toxic: It is physiologically inert, and it has no adverse reactions when it is implanted in the body as
an artificial blood vessel and an organ for a long time.
Gaskets produced from this material have all these advantages and properties.
