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 applications
High chemical resistance.
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 + Bronze 40
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
Bronze-filled PTFE provides good creep resistance due to the copper/tin alloy that it contains. This type of plastic exhibits improved thermal conductivity, with a high load-bearing capacity which is why it is most often used in hydraulic systems. The bronze enhances dimensional stability due to improved hardness and compressive strength.
