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.
