Fluorcarbonresins have following important characteristics::
● high heat-resistance during permanent operation
– HELUFLON®
-FEP 205 °C
– HELUFLON®
-PTFE 260 °C
● outstanding resistant against dielectric strength
● constant dielectric characteristics
● moisture absorption
● resistant against nearly all chemical products
● insensitive environmental uences, weatherproof and resistant irradiation from the sun and
temperature uctuations
● good mechanical characteristics, formation cracks, wear-resistant
● low coef cient friction
● action light (also uv)
