| 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 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. Teflon™ 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.Information provided by Chemours. |
