PFA is the abbreviation of perfluoalkoxy alkane, the Chinese name is called soluble polytetrafluoroethylene. The performance of PFA is similar to PTFE and FEP, with excellent chemical resistance, electrical insulation and heat resistance, PFA has excellent heat resistance, chemical resistance and mechanical strength, so it is widely used in many fields.
First, PFA is widely used in the electronics industry, because of its high temperature stability and chemical resistance, it can be used as an insulating material and packaging material in electronic equipment. For example, in semiconductor manufacturing, PFA can be used as an encapsulation material for high-purity metals and ceramics to prevent contaminants from entering the inside of the device. In addition, PFA can also be used to make insulation layers for cables and connectors to improve electrical performance.
Secondly, PFA is also widely used in the medical field, because of its biocompatibility and low toxicity, PFA can be used as a material for medical devices. For example, it can be used to make implants such as artificial joints and heart valves for better durability and comfort. In addition, PFA can also be used to make medical supplies such as hand gloves and catheters to ensure patient safety and hygiene.
In addition to electronics and medical devices, PFA is also used in other fields. For example, in the aerospace sector, PFA can be used as a fireproof coating and sealing material for aircraft box rockets to improve safety. In the automotive industry, PFA can be used to manufacture high-performance automotive components such as brake systems and suspension systems. In addition, PFA can also be used to make food processing equipment and lining materials to ensure food hygiene and safety.
In short, PFA is a polymer material with excellent properties, which is widely used in electronics, medical, aerospace and automotive fields. Its high temperature resistance, chemical resistance and mechanical strength make it an ideal material now. With the continuous progress of science and technology, we can expect the application of PFA to be more widely diversified in the future.

When choosing the right fluoropolymer for your process, consider some significant performance differences between the two fluoropolymers. The difference in alkoxy substituents allows PFA to be fused by conventional injection molding and screw extrusion techniques, while PTFE cannot. The PFA is more flexible, but has a lower flexural life, so it cannot withstand the ability to fold repeatedly. PTFE has slightly higher heat resistance, but is lacking in comparison to fluidity, creep resistance, and thermal stability. The melting points of PFA and PTFE are 260°C and 327°C, respectively. Although PFA has better salt spray resistance, water absorption and weather resistance have a greater impact on PFA than PTFE. Finally, the most significant difference between the two is that the dielectric strength of PFA is 3-4 times that of PTFE.
PFA forming and processing
PFA resin includes emulsion, powder, granule and other forms, the difference is that the melting point of pfa is 290~312ºC, the melting finger is within the range of 0.8-30g/10min, the molding temperature is between 350~410ºC, and the pfa resin is used in molding, extrusion molding, injection molding and other processing processes
When the melt finger of PFA extrusion molding is greater than 3.0g/10min, it can be processed by extrusion molding. The process and equipment of PFA extrusion molding can be used in common with the process and equipment of polyperfluorinated ethylene (FEP). When the melt finger of PFA product is in the range of 0.8~3.0g/10min, the molecular weight is relatively high and the viscosity is large. It is not easy to flow, and it is suitable for manufacturing molding by molding injection molding melting finger in the range of 16~30g/10min, which requires the production of various complex shapes of parts such as aerospace industry, electronic and electrical parts, medical chemical testers and other purposes
