Zusammenfassung:A fluorocarbon rubber base compsn. comprises (a) 50-95 wt.% fluorocarbon elastomer having a Mooney viscosity of 5-160 (b) 5-50 wt.% of an amorphous silicone resin having a degree of substitution of 0.9-1.8 (c) 0-40 wt.% of polydiorganosiloxane gum and (d) 0-40 wt.% of hydrocarbon polymer elastomer. Also claimed is a cured fluorocarbon rubber obtained from the compsn.
