PFA rod is very similar to FEP rod, but pfa welding rod has better mechanical properties at higher temperature.PFA plastic welding rod has better high temperature resistance which is very similar to PTFE. PFA plastic welding sticks has many advantages over PTFE and FEP.PFA plastic welding strips is widely considered as the best soluble fluorine copolymer to replace ptfe rod and fep rod.
The basic characteristics of PFA can be summarized as follows: 1) PFA plastic welding wire has better flexibility and improves the melt viscosity of polymer, so PFA rod can be processed more easy. 2) At room temperature,the physical and mechanical properties of PFA rod are similar to PTFE. 3) The stress scracking of PFA rod is better than that of FEP rod. 4) PFA rod is anti all chemical reagents and solvents. 5) PFA rod has good permeability and has good weather resistance and atmospheric aging resistance. PFA rod can be used outdoors for a long time. 6) PFA rod has excellent dielectric properties.
