Teflon® FFR 430

DuPont™ Teflon ® FFR 430 fluoroplastic foam resin has been developed with a superior nucleant package to provide improved foam cell structure and a broader processing window. It has the lowest melt flow (7) of the FFR resins, making it best suited for the larger plenum coax cables, particularly when the lowest smoke generation is a key design consideration. The foamed insulation of Teflon ® FFR 430 fluoroplastic foam resin provides high-speed data transmission with minimal distortion, and good cable structural return loss with reduced attenuation. FFR 430 offers cable designers opportunities for reducing cable size with cable weight savings or the use of larger conductors to construct low-loss cables without the need for increased dielectric dimensions.

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 insulation. Achievable cell size and void content will vary based on wall thickness and processing conditions.
