RUBBER COMPOSITION

摘要

A rubber composition comprising 100 parts by weight of a rubber mixture consisting of 70 to 95 wt% of a solid rubber and 30 to 5 wt% of a liquid rubber reactive with the solid rubber and 450 to 1000 parts by weight of a powdered magnetic filler. This rubber composition is obtained by incorporating a magnetic rubber composition of the prior art comprising a solid rubber and a powdered magnetic filler with a liquid rubber reactive with the solid rubber, whereby the rubber composition is lowered in viscosity and improved in processability without impairing the high magnetic force inherent in the magnetic filler or the physical properties inherent in rubber, while it retains excellent heat resistance and flexibility of moldings.
