POLYTETRAFLUOROETHYLENE "PTFE"
PTFE displays the greatest stability under heating of all the techno-polymers: the maximum temperature for use over short periods is about 300oC, and over long periods about 250oC.
Its solidity and rigidity are low, while its stretching to breaking point is greater than 100%. Its shrinkage following processing is high.
Its advantages lie in the vastness of the temperature range within which it can be used, its universal chemical stability, its insolubility in all known solvents at temperatures less than 300°C, its resistance to atmospheric agents, its excellent electrical and dielectric characteristics and its excellent non-stick property that allows it to slide on all materials.
Fields of Use:
The engineering sector for the production of gaskets subject to static and dynamic stresses, pistons and other machinery parts, linings and coatings and gearings produced from semi-finished products such as pipes, hollow bars, solid round bars and sheets.
