Teflon® FFR 770
Teflon ™ FFR 770 is a fluoroplastic resin compounded with a foam nucleating package. This resin is supplied as white pellets and is used in a nitrogen gas-injected foam extrusion process to produce uniform foam cells in the dielectric insulation. Foaming the fluoroplastic reduces its dielectric constant, providing opportunities for miniaturization and weight savings. Foamed insulation of Teflon ™ FFR 770 produces cables for high frequency signal transmission with minimal distortion.
Teflon ™ FFR 770 is ideal for producing foamed primary dielectric insulation for twisted pair cables and miniature coaxial cables. A typical cable core would have conductor sizes of 32 AWG or greater, wall thickness of 0.004 in or greater, with void content from 20% to 65%.
These voids are closed cell in nature and range from 0.0007 in (0.018 mm) to 0.0013 in (0.033 mm) in diameter. Achievable void content will vary based on wall thickness and processing conditions.
