Thermoplastic Fluoropolymers
All thermoplastic fluoropolymers are melt extrudable alternatives to PTFE, and are processed in corrosion-resistant equipment. The various thermoplastic fluoropolymers differ in their molecule structure and number of fluorine atoms. It is this difference that will give them their distinctive properties, whilst still maintaining some of the unique properties of PTFE.

FEP (Fluorinated EthylenePropylene)
FEP is a copolymer of tetrafluoroethylene and hexafluropropylene with a linear molecule chain. FEP has almost the same characteristics as PTFE and is transparent, even though it is a semi-crystalline polymer.

• Excellent low friction properties and non-stick characteristics.
• Excellent chemical resistance.
• Outstanding continuous service temperature between -200°C and +200°C.
• Extremely smooth surface.

PFA (PerFluoroAlkoxy)
PFA is a transparent perfluoroalkoxy copolymer that is considered to be the thermoplastic fluoropolymer with the closest properties to PTFE, whilst being melt processable.

• Low friction properties and non-stick characteristics.
• Outstanding chemical resistance.
• Outstanding service temperatures up to +260°C.
• High light transmission.

ETFE (EthyleneTetraFluoroEthylene)
ETFE is a copolymer of tetrafluoroethylene and ethylene. ETFE is stiff, tough and has a higher resistance to wear than most fluoropolymers.

• Excellent non-stick characteristics.
• Low liquid permeability.
• Good resistance to radiation.
• High light transmission.

PVDF (PolyVinyliDeneFluoride)
PVDF is a polymer of vinylidenefluoride. PVDF is stiffer and has a higher mechanical strength and resistance to wear than ETFE.

• Good chemical resistance.
• Excellent abrasion resistance.
• Excellent aging resistance.
• Smooth surfaces.
