Fluoropolymer Resins

Below is a list of Fluoropolymer resins and a brief summary of their properties and physical make up.

Fluorinated Ethylene Propylene

Fluorinated Ethylene Propylene or FEP is a type of Fluoropolymer Resin manufactured from a  copolymer of hexafluoropropylene and tetrafluoroethylene. It differs from the PTFE resins in that it ismanufactured using a melt-process technique. FEP is very similar in composition to the fluoropolymers PTFE  and PFA. FEP & PFA share some of the same properties as PTFE  like low friction and non-reactivity, but are more easily formable. FEP is softer than PTFE and melts at 260 °C; it is highly transparent and resistant to sunlight and UV rays.


ECTFE (Ethylene ChloroTriFluoroEthylene) was designed to provide excellent chemical resistance in heavy duty corrosion applications. It is a partially fluorinated polymer (a fluoropolymer), semi-crystalline and can be processed in the melt. Chemically it is a copolymer of ethylene and chlorotrifluoroethylene. It is more common brand name is Halar.


Polyvinylidene fluoride, or polyvinylidene difluoride (PVDF) is a highly non-reactive and pure thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride.

PVDF is a specialty plastic material in the fluoropolymer family; it is used generally in applications requiring the highest purity, strength, and resistance to solvents, acids, bases and heat and low smoke generation during a fire event. Compared to other fluoropolymers, it has an easier melt process because of its relatively low melting point of around 177 °C.

Perfluoroalkoxy Alkane

Perfluoroalkoxy Alkanes or PFA is a type of fluoropolymer. In terms of its properties, PFA polymers are similar to polytetrafluoroethylene (PTFE). The big difference is that the alkoxy substituents allow the polymer to be melt-processed. The physical and chemical make up of PFA results in a material that is more translucentand has improved flow, creep resistance, and thermal stability close to or exceeding PTFE.


Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. PTFE is a solid fluorocarbon, as it is a high-molecular-weight compound consisting wholly of carbon and fluorine. PTFE is a hydrophobic material: neither water nor water-containing substances wet PTFE. Polytetrafluoroethylene has one of the lowest coefficients of friction of any solid. PTFE is the most widely used and most common Fluoropolymer resin available.

Polyetherether Ketone

Poly ether ether ketone (PEEK) has attractive properties like good abrasion resistance, low flammability and emission of smoke and toxic gases, resistance to radiation and high temperature steam, and low water absorption.
