Usage

Description

Perfluoroethylene propylene copolymer, also known as PFA, is a copolymer of tetrafluoroethylene and hexafluoropropylene. It possesses properties similar to polytetrafluoroethylene resin, with a higher coefficient of friction. The repeating structure of the molecule is [–CF2–CF2–CF2CF(CF3)–]n. PFA is known for its excellent chemical resistance, high-temperature stability, and non-stick properties, making it a versatile material for various applications.

Uses

Used in Wire and Cable Insulation:
Perfluoroethylene propylene copolymer is used as an insulating material for wires and cables due to its excellent chemical resistance, high-temperature stability, and dielectric properties. These characteristics ensure the safety and reliability of electrical systems.
Used in Pipe Linings:
PFA is utilized as a lining material for pipes, providing protection against corrosion and chemical attack. Its non-stick properties also help reduce friction and improve the flow of fluids through the pipes.
Used in Processing Equipment Lining:
In the processing industry, PFA is used as a lining for equipment to protect against chemical reactions and high temperatures. Its resistance to a wide range of chemicals and its ability to withstand high temperatures make it an ideal choice for various processing applications.
Used in Filtration Screening:
Fibers made from perfluoroethylene propylene copolymer are used in filtration screening and mist separators. The material's chemical resistance, high-temperature stability, and non-stick properties contribute to efficient and reliable filtration processes.
Used in Medical Applications:
Although not explicitly mentioned in the provided materials, PFA is also used in the medical industry for its biocompatibility and chemical inertness. It is commonly found in components of medical devices, such as tubing and seals, where its non-stick and heat-resistant properties are advantageous.

Production Methods

The elastomer is prepared by high-pressure, free-radical aqueous emulsion polymerization. Fluorine is substituted for hydrogen. The initiators are organic or inorganic peroxy compounds, such as ammonium persulfate, and the emulsifying agent is usually a fluorinated acid soap. Applications include tubing, hose, and gaskets.
