Common uses: Electrical applications in aircraft, robots, electrical machines, gaskets, pipes, filters, self-lubricating bearings, coating in pans, foil, surface coating in chemical equipment, electrical insulation material, etc.
The benefits of PTFE plastic
High chemical resistance.
Excellent sliding properties.
Not attacked by acids, bases, and most organic solvents.
Withstands up to + 260 ° C continuously.
Tough at low temperatures down to -160 ° C.
Lowest friction of all plastics.
Not degraded by UV radiation.
Not attacked by microorganisms.
Good electrical and dielectric properties.
Very low water absorption.
The restrictions of PTFE plastic
High melt viscosity makes the material difficult to work with.
Poor creep resistance.
High density relative to other plastics.
Attacked by molten alkali metals, fluorine gas, oxygen difluoride, and chlorine trifluoride (except PTFE).
PTFE material, with the chemical name polytetrafluoroethylene, is a semi-crystalline fluoropolymer with many unique properties. This fluoropolymer has unusually high thermal stability and chemical resistance as well as a high melting point. To improve the mechanical properties, PTFE plastic can be reinforced with additives such as
Due to its structure, polytetrafluoroethylene is formed into semi-finished products in a compression process and then processed in cutting/cutting machines.
