Abstract:

Filler-rubber systems containing various chemical modifications of silica and fibrous talc as fillers, have been evaluated at 500 F. after aging at 500 F. Trimethylsilyl TMS silicas are more suitable than triphenyl silicas. Fibrous grades of talc were superior as non-reinforcing fillers. Best improvement was obtained with combination of TMS silica and fibrous talc modified by chlorosilanes. Additional incorporation of vinyl chlorosilane approved high temperature elongation. Author
