DIENE-BASED RUBBER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a diene-based rubber composition having an excellent high-temperature modulus of elasticity and an excellent temperature dependence of modulus of elasticity. SOLUTION: The diene-based rubber composition comprises 100 pts.wt. of diene-based rubber, 0.1-30 pts.wt. of silk powder and 10-100 pts.wt. of carbon black. The pneumatic tire uses the rubber composition. COPYRIGHT: (C)2009,JPO&INPIT
