PFA rod is made from PFA resin and prepared by the technology of extrusion and molding. It can be machined into various sealing parts and electric components. It can be used at the temperature range of -200 ~ +260C degree PFA (Polyfluoroalkoxy) owns excellent chemical stabilities, thermal properties and dielectric properties as PTFE. Good self-lubricating properties, flame resistance, and aging resistance. It has prominent folding endurance and stress cracking resistance. Its mechanical strength is 1.6 times as strong as PTFE. |

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. |
