PFA( Perfluoroalkoxy alkane) it kept a PTFE excellent chemistry stability, low, high temperature resistance, dielectric property, self-lubricating, anti-sticking, , ageing resistance, folding and cracking resistance are the outstanding characteristic of it, its mechanical strength in high temperature is more than 1.6 times as PTFE.technical index of PFA: | Index name | Unit | Figure | | sheetrod product | tubefilm product | | Density | g/cm3 | 2.122.17 | | Tensile strength | Mpa | 22 | 15 | | Elongation ratio | % | 280 | 260 | | Temperature range | | 200250 | | Dielectric strength | Kv/mm | 15 |
