  • Fluoropolymers (PCTFE)

    Fluoropolymers are high-performance plastics with strong Carbon-Fluorine bonds. This bond provides the compounds with excellent chemical resistance and good mechanical properties. They are an excellent choice for a multitude of uses including pharmaceutical, cryogenic, high-temperature and low friction applications where their properties in these areas are unequalled.

    Description
    PCTFE
    Thermoplastic Chlorofluoropolymer    		 Min: -240°C
    Max: +132°C

    90 Shore D

    A thermoplastic chlorofluoropolymer, and commonly referred to as PCTFE or Kel-F®*. It has excellent chemical and permeation resistance and the lowest water vapor transmission rate of any plastic.
    PVDF-CD72
    Thermoplastic Fluoropolymer    		 Min: -60°C
    Max: +150°C

    72 – 82 Shore D

    A thermoplastic fluoropolymer produced via the polymerisation of Vinylidene Difluoride. It has superior creep resistance and is resistant to most solvents, acids and alkalis while having a low moisture uptake.
    FEP-TD55
    Fluorinated Ethylene Propylene FEP    		 Min: -250°C
    Max: +205°C

    55 – 60 Shore D

    A melt processable semi crystalline fluoropolymer which is commonly referred to as FEP. The material has excellent temperature and chemical resistance properties with a better impact resistance than that of PTFE.
    ETFE-D67
    Ethylene Tetra Fluoro Ethylene    		 Min: -100°C
    Max: +150°C

    62 – 72 Shore D

    A fluorine based plastic specifically designed to provide increased corrosion and strength resistance over a wide temperature range. It has excellent resistance to ultra-violet light and high energy radiation.
    PFA-OD63
    PerFluoroAlkoxy PFA    		 Min: -200°C
    Max: +250°C

    60 – 65 Shore D

    A copolymer of TetraFluoroEthylene and Perfluoroethers specifically designed to provide corrosion, creep resistance and thermal resistance close to that of PTFE.
    ECTFE
    Ethylene Chlorotrifluoroethylene    		 Min: -75°C
    Max: +150°C

    70 – 80 Shore D

    Excellent dimensional stability and mechanical properties; stiffer and stronger than many of the other types of fluoropolymer materials. Has a low coefficient of thermal expansion and very low moisture absorption.
