Chemfilm® DF1400 and DF1471 are multilayer cast PTFE films produced using a proprietary process.
The 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.
The DF1471 is a fully conductive PTFE that is also available with a conductive FEP surface.
