CHEMFILM DF1400 and DF1471 are multilayer cast PTFE films produced using a proprietary process. DF1400 has a non-conductive, fully fused, PTFE core coated with a conductive fluoropolymer formulation designed to be applied over jacketed wire and cable using standard tape-wrap equipment. DF1471 is a fully conductive PTFE that is also available with a conductive FEP surface.
CHEMFILM DF1700 and DF1900 cast films are heat bondable multilayer castfluoropolymer films produced using a proprietary process. These films have a PTFE core with a thin layer of FEP or PFA on one surface.
