Abstract
A rubber composition, which comprises 100 parts by weight of a rubber mixture consisting of 70-95 wt. % of solid rubber and 30-5 wt. % of liquid rubber reactive on the solid rubber, and 450-1,000 parts by weight of magnetic powder. The rubber composition has an improved processability by adding liquid rubber reactive on solid rubber to the conventional magnetic powder-containing rubber, without any deterioration of physical properties proper to the rubber, while maintaining a high magnetic force proper to the magnetic powder, keeping the lower viscosity of rubber compound and holding distinguished heat resistance and flexibility of moldings.
