Heat-resistant vibration damping rubber composition
摘要:
A heat-resistant vibration damping rubber composition wherein 20-80 parts by weight of a powder of silica having a BET specific surface area of 20-70 m2/g is mixed with 100 parts by weight of an ethylene-propylene-diene rubber material, and a sulfur-containing silane coupling agent and a mercapto-based silane coupling agent are both mixed with the ethylene-propylene-diene rubber.
