Fluoroplastics are a class of synthetic materials with excellent performance, including PTFE, ETFE, FEP, PFA, and PVDF. These materials are widely used in various fields due to their heat resistance, weather resistance, cold resistance, chemical resistance, solvent resistance, excellent electrical insulation performance and high-frequency electrical properties, as well as non-stick, self-lubricating, and low friction coefficient characteristics.
PTFE (Polytetrafluoroethylene): PTFE is a polymer formed by the polymerization of tetrafluoroethylene monomers and is known as the "king of plastics." It has extremely high heat and cold resistance, with a long-term service temperature range of -200°C to +260°C. PTFE's chemical resistance is excellent, almost resisting the erosion of all chemical substances. In addition, PTFE has a very low friction coefficient, providing excellent lubricity and non-stick properties. PTFE is widely used in the chemical, electronic, medical, and aerospace fields.
ETFE (Ethylene-Tetrafluoroethylene Copolymer): ETFE is a lightweight, heat-resistant film material with excellent chemical resistance, wear resistance, and radiation resistance. ETFE film materials are widely used in the construction field, such as roof and wall materials, favored for their light weight, toughness, high tensile strength, and weather resistance.
FEP (Fluorinated Ethylene-Propylene Copolymer): FEP is a melt-processable fluoroplastic similar to PTFE, with similar chemical resistance and non-stick properties. FEP has a long-term service temperature range of -65°C to +200°C and is suitable for wire and cable insulation, anti-corrosion equipment, and sealing materials.
PFA (Perfluoroalkoxy Copolymer): PFA is a melt-processable fluoroplastic with excellent chemical and radiation resistance. PFA has a long-term service temperature up to +260°C and is suitable for the semiconductor industry, medical devices, and high-temperature wire and cable insulation.
PVDF (Polyvinylidene Fluoride): PVDF is a fluoroplastic with piezoelectric properties, good chemical corrosion resistance, high-temperature resistance, oxidation resistance, weather resistance, and radiation resistance. PVDF has a long-term service temperature range of -40°C to +150°C and is widely used in the chemical, electronic and electrical, and fluorocarbon coating fields.
These fluoroplastics play an important role in modern industry and technology due to their unique properties.
