Document Type and Number:
WIPO Patent Application WO/2015/133465
Kind Code:
A1
Abstract:
A magnetic rubber composition containing a rubber (A), a heat-curable resin (B), and a magnetic powder (C), and in which the mass ratio (A/B) of the rubber (A) and the heat-curable resin (B) is 0.2-5, and the mass ratio [C/(A+B)] of the magnetic powder (C) relative to the total mass of the rubber (A) and the heat-curable resin (B) is 0.5-20. Thus, a magnetic rubber molded article having superior flexibility and superior abrasion resistance, and a magnetic encoder using the same, can be provided.
