PFA is developed as a melt processable fluoropolymer, it is a co- polymer of tetrafuoroethylene and perfluoroalkoxy monomer. It has excellent mechanical strength outstanding dielectirc properties & is unaffected by virtually all solvents & chemicals even at high temperature of 240C to 260C.

Processing Polymers such as PFA by injection molding is extremely critical as the process requires close monitoring with controlled heating and cooling of the assemblies during the entire molding stage. Our lining technique its own advantages over the conventional method of lining where Transfer Molding System are used.
