Key Materials and Applications
ETFE (Ethylene-Tetrafluoroethylene)
Properties: Lightweight, radiation-resistant, easy to process, strong and tough, chemically stable, weather-resistant, with excellent optical and electrical properties.
Applications: Widely used in wire and cable, chemicals, construction, and agriculture. Specific applications include high-temperature measurement cables for aircraft, spacecraft, ships, transportation equipment, and nuclear power plant control rooms. ETFE films are also utilized in automotive windshields, food industry conveyor belts, solar receivers, and medical packaging.
PFA (Perfluoroalkoxy Resin)
Properties: Excellent corrosion resistance, high and low-temperature stability, weather resistance, and thermoplastic processability.
Applications: Predominantly used in the semiconductor industry for manufacturing silicon wafer carriers, piping, and semiconductor parts. It is also employed in high-purity semiconductor piping, pharmaceutical processing, and ultrapure water treatment.
PEEK (Polyetheretherketone)
Properties: High temperature resistance, excellent mechanical properties, chemical resistance, and wear resistance.
Applications: Used in aerospace, automotive, medical, and electronic industries due to its unique combination of properties. PEEK films are suitable for applications requiring high strength, stiffness, and durability at elevated temperatures.
PVDF (Polyvinylidene Fluoride)
Properties: High melting point, good plasticity above the melting point, chemical resistance to inorganic acids and bases, but less resistant to organic acids and solvents.
Applications: Utilized in the manufacture of chemical piping, pumps, valves, storage tanks, and corrosion-resistant gears, bearings, and sealing gaskets. PVDF films are also employed in building materials, coatings, and electrical insulation.
