The chemical resistance of polymers with high fluorine content is exceptionally high. The electrical insulating and dielectric properties of these materials are also very good.
Fluorine-polymers are resistant against nearly all known chemical compounds.
Fluorine-polymer has a smooth surface of extremely low surface tension which is why virtually nothing adheres to this material.
Fluorine-polymer is moisture rejecting, doesn’t swell and is not be damaged by welding.
Fluorine-polymer is used, where conventional material wouldn’t resist the environmental conditions.
Fluorine-polymer is applied in the civil and military sector as well as in the aviation- and aerospace technology.
Fluorine-carbon-resins have following important characteristics:
- high heat-resistance during permanent operation
- HELUFLON®-FEP up to 250°C
- HELUFLON®-PTFE up to 260°C
- outstanding resistant against dielectric strength
- constant dielectric characteristics
- no moisture absorption
- resistant against nearly all chemical products
- insensitive temperature fluctuations
- good mechanical characteristics, no formation of cracks, wear-resistant
- low coefficient of friction
- light resistant (also UV)
