Filler systems in RGD resistant compounds strengthen material structure and reduce gas permeability. Carbon black, silica, and specialized fillers reinforce polymer matrices. Filler particles obstruct gas diffusion pathways through the material. Proper filler selection and dispersion balance mechanical properties with RGD resistance. Over-filling hardens compounds excessively, while u... https://globalsealstech.com/product/rgd-rapid-gas-decompression-o-rings/
