PFA

Perfluoroalkoxy (PFA) is a semi-crystalline, fully fluorinated, melt-processable fluoropolymer. It is a modified polymer of polytetrafluoroethylene (PTFE) by introducing an F₃CO^- group to the PTFE frame structure. PFA has a broad application ranging from biomedical and aerospace to corrosive environments in the chemical industry.

Alfa Chemistry is a leading global supplier of PFA. We are committed to providing you with a wide range of PFA materials, including PFA rods, films, granules and powders. Whether it's chemical processing, electronics, automotive, aerospace or medical applications, Alfa Chemistry has a comprehensive solution for you.

Performance Characteristics

The main performance characteristics of PFA are as follows:

• PFA shows comparable mechanical properties as fluorinated ethylene propylene (FEP) below 200 °C, and performs comparable mechanical properties as PTFE above 200 °C.
• The thermal stability of PFA is almost the same as that of PTFE and better than that of FEP.
• Compared with PTFE, PFA film has better transparency.
• Since PFA is perfluorinated like FEP, it retains high chemical resistance, low surface energy and good electrical insulation properties.
• PFA is unaffected by prolonged exposure to direct sunlight, wind, rain and exhaust gases.

Applications

PFA has a wide range of applications in various industries. Its typical applications are as follows:

• Chemical Processing: PFA is commonly used in pipelines, tanks, valves, and as the liner in vessels that convey corrosive chemicals due to its excellent chemical resistance.
• Electronics and Electrical Industry: Due to its excellent electrical insulation properties, PFA is used in wire insulation, cable jackets, and connectors to ensure reliable and efficient electrical performance.
• Automotive and Aerospace: In the automotive and aerospace industries, PFA is widely used for fluid transfer applications or for air passage requiring excellent chemical resistance.
• Medical and Pharmaceutical: Components manufactured or coated with PFA materials have excellent resistance and are an effective solution to avoid contamination by biological and chemical elements. PFA has become the best material for medical tubing, surgical instruments and fluid handling systems.
• Semiconductor Manufacturing: PFA can be made into specialized tubing for semiconductor manufacturing units, and its unique molecular structure resists ionic and metallic contamination.
