CHLOROPRENE RUBBER COMPOSITION, VULCANIZED MOLDED ARTICLE, AND ANTI-VIBRATION RUBBER

摘要

Provided are a chloroprene rubber composition that provides a vulcanized molded article having further improved heat resistance without harming the anti-vibration rubber properties or mechanical properties represented by the durometer hardness and elongation at break, a vulcanized molded article of this composition, and anti-vibration rubber thereof. A chloroprene rubber composition containing 100 parts by mass of chloroprene rubber, from 0.1 to 10 parts by mass of active zinc white having an average particle size of from 0.05 μm to 0.35 μm, a particle size range of from 0.01 μm to 1.0 μm, and a specific surface area of from 10 m2/g to 150 m2/g, and from 15 parts by mass to 200 parts by mass of carbon black having an average particle size of from 70 nm to 600 nm and DBP oil absorption of from 15 mL/100 g to 60 mL/100 g.
