Cutting (turning, milling, drilling, sawing): Traditional metalworking – or in certain cases, woodworking tools – carbon steel, rapid steel, hard metal, diamond can be used in sharp design only. Cooling is recommended, which allows high cutting rates e. g. v = 200–400 m/min for turning and milling, v = 50–100 m/min for drilling.
Adhesive bonding: not suggested.
Available only for request. FEP belongs to the melt fusible material family. It has good diffusion coefficients to PTFE. FEP has excellent ductility and wide range of dimensions.
Available only for request. Just like FEP it belongs to the melt fusible material family. It has excellent transparency among fluoropolymers. It has excellent chemical resistance.
Among the fluoro-polymers PFA has excellent heat stability. Comparing to natural PTFE it has better creep resistance and mechanical properties. Welding is possible. PFA available in thin-walled tubes. Different colours are available.
A version of the “natural” PTFE reinforced with carbon and graphite. It has greater rigidity, dimensional stability, smaller creeping, it is electrically Esd material. Its wear resistance is better than that of “natural” PTFE.
A version of the natural PTFE reinforced with 25% glass fiber. It has greeter rigidity, dimensional stability and smaller creeping in comparison with the “natural” PTFE.
Unreinforced, unfilled version. Especially used in positions under small mechanic stress where the objective is resistance to chemicals, lining or small friction. It can be manufactured using various technologies, which influence the size selection.
