what is fep polymer
FEP plastic is a copolymer of tetrafluoroethlene and Hexafluoropropylene. This melt-processible fluoropolymer exhibits excellent resistance to heat, wear and chemicals. Polymer Plastics offers besides Dupont Teflon FEP, Daikin Neoflon FEP. It is like PTFE in that it is a soft material with low tensile strength, and low wear resistance. FEP is chemically inert and insoluble in all but a few exotic solvents. Like TFE, FEP is manufactured by DuPont and sold under the name of Teflon FEP.
