Fluoropolymers are a family of high-performance plastics characterized by carbon-fluorine bonds. They exhibit exceptional chemical resistance, thermal stability, and electrical insulation properties.

PTFE (Polytetrafluoroethylene)

The most widely known fluoropolymer, commonly called Teflon. PTFE has the lowest coefficient of friction of any solid material and can operate from -200°C to +260°C.

PFA (Perfluoroalkoxy)

PFA combines PTFE-like properties with melt-processability. Ideal for semiconductor, chemical processing, and wire insulation applications.

FEP (Fluorinated Ethylene Propylene)

FEP offers excellent clarity and is melt-processable. Used in wire insulation, chemical-resistant linings, and film applications.

PCTFE (Polychlorotrifluoroethylene)

PCTFE provides ultra-low moisture permeability and excellent dimensional stability. Critical for pharmaceutical blister packaging and cryogenic seals.

ETFE (Ethylene Tetrafluoroethylene)
