High frequency and low dielectric FEP（DS618HD）
High frequency and low dielectric FEP is the copolymer of tetrafluoroethylene (TFE) and
hexafluoropropylene (HFP), which has better dielectric loss at high with high frequencies, good
thermal stability, outstanding chemical inertness, low coefficient of friction and excellent
electrical insulation. It can be processed by thermoplastic method.
