PFA, also known as soluble polytetrafluoroethylene (soluble PTFE), PFA has similar properties to PTFE and FEP. PFA is produced in order to make up for the difficulty of PTFE processing, PFA processing can be divided into: injection molding, extrusion, molding. |
PFA rod is made of imported high quality raw materials and processed by special technology. PFA rods retain most of the advantages of PTFE, while being able to undergo thermal melting due to reduced crystallinity, lower melting point and significantly reduced melt viscosity. Compared with FEP, it has superior resistance to high temperature and stress cracking. PFA rods also offer excellent flexibility and have higher mechanical strength than PTFE at high temperatures. High and low temperature resistance, long-term operating temperature range of -200ºC~ 260ºC. It has excellent chemical resistance, corrosion resistance to all chemicals, and low friction coefficient. It also has excellent electrical properties, with insulation that is not affected by temperature and excellent radiation resistance. Conforms to VO class flame retardant standard. PFA rod is made of imported PFA resin, which has excellent chemical resistance, high temperature resistance, crack resistance and good transparency. Compared to other fluoropolymer tubes, PFA has higher polymer purity and higher continuous operating temperature. |
Application PFA is widely used in chemical anit-corrosion,mechanical seal, semiconductor, electrical insulation, pump&valve fluid, aviation and other relevant industries. |
