Detail of Lab Casting Machine For PFA Films
Working process of Lab Casting Machine For PFA Films
PFA application:
1, suitable for the production of corrosion resistant parts, wear resistant parts, seals, insulation parts and medical instrument parts.
2, high temperature wire, cable insulation layer, anti-corrosion equipment, sealing materials, pump valve bushing, and chemical containers.
1. Crystallizing material, small moisture absorption. Can be processed into products by the usual thermoplastic processing method.
3, poor liquidity, easy to decompose, decomposition of corrosion gas. The molding temperature should be strictly controlled not to exceed 475 degrees, the mold should be heated to 150-200 degrees, and the pouring system should have little resistance to the material flow.
4, translucent granule, injection molding, extrusion molding. Forming temperature 350-400 degrees, 475 degrees above easy to cause discoloration or bubble. And be aware that demoulding can be difficult.
5, because the molten material has corrosion effect on the metal, long-term production, the mold needs plating chromium treatment.
PFA, FEP and PTFE have similar chemical properties, but Dankai FEP can only be used below 200 degrees, and PTFE can not be injected.
It can be seen that PFA is a relatively new kind of fluorine plastic in China, which has strict processing conditions but excellent performance. It is mainly used in the chemical industry with high temperature and corrosion resistance as well as the fluorine plastic wire and cable industry.
PFA Film main uses are as follows:
