Ethylene Tetrafluoroethylene (ETFE) is also a fluorocarbon based polymer, a kind of plastic.  ETFE is a thermoplastic copolymer that is derived from the polymerization of Ethylene and Tetrafluoroethylene monomers.  This resin is extremely tough and abrasion resistance. It was designed to have high corrosion resistance, low coefficient of friction and strength over a wide temperature range. In addition to this it has a high melting temperature and does not emit toxic fumes when ignited.

ETFE coating is a proven fluoropolymer in the chemical and petrochemical industries.  ETFE is renowned for its unique properties and design versatility.  It has the ability to solve the toughest material problems of industrial equipments and components.

ETFE coatings provide excellent resistance to attacks by chemicals and solvents that can cause rapid deterioration of other plastics.  ETFE is inert to strong mineral acids, inorganic bases, halogens and metal salt solutions.

In addition to this ETFE coatings will have excellent mechanical strength, stiffness and abrasion resistance.  It will be an ideal in such applications where abrasive slurries accelerate wear and degradation of alternative materials.

Fluorinated Ethylene Propylene (FEP) is a copolymer of hexafluoropropylene and tetrafluoroethylene.  It is relatively a soft thermoplastic with lower tensile strength, wear resistance and creep resistance than any other engineering plastics.  However, FEP coatings are chemically inert and have a low dielectric constant.

Properties of FEP Coatings

• High degree of stress crack resistance
• Low coefficient of friction
• Exceptional dielectric properties
• Heat resistance
• Retention properties
• High transparency rate with good transmittance of ultra violets and visible wavelengths
• Long term weather resistant
• Excellent resistance to ozone, sunlight and weather
• Lowest refractive index of all thermoplastics with low light reflection

Important applications of FEP coatings are linings for pipes, linings for chemical equipment including roll covers, cable applications, aircraft wire, plenum cable, fire alarm cable and well logging cable.  FEP film is also used as glazing in solar energy collectors.
