ETFE MATERIALS
The fluorine-based plastic ethylene tetrafluoroethylene (ETFE) is a fluorine-based material. It was made to withstand corrosion and maintain strength over a wide temperature range. ETFE is a polymer with the source name poly (ethene-co-tetrafluoroethene). Tefzel is another brand name for this product. ETFE has a high melting temperature, as well as good chemical, electrical, and high-energy radiation resistance. ETFE Materials produces hydrofluoric acid when it is burnt.
ETFE is an ethylene-tetrafluoroethylene modified copolymer. It has a medium stiffness, making it ideal for chemical tank linings that require weldability and the ability to adapt to curved metal or FRP surfaces. ETFE is frequently used in applications requiring high mechanical toughness, moderate stiffness, and chemical resistance.
ETFE IS WIDELY USED FOR:
- Pump housings and pipe linings
- Impellers for abrasive slurries
- Fluid handling and chemical processing equipment
- Wet bench equipment
- Oxygen respirator components
- Military / defense equipment
- Food processing equipment
- Radomes
PERFORMANCE CHARACTERISTICS:
- Chemically inert to a wide range of industrial chemicals and solvents
- Exceptional dielectric insulation properties
- Rugged, good abrasion resistance, and impact strength
- May be welded with hot air welding equipment
- High resistance to outdoor weathering
- Radiation and heat sterilization resistant
COMMON BRANDS:
- Tefzel®
