HIGH MODULUS LOW HYSTERESIS RUBBER COMPOUND FOR PNEUMATIC TIRES

摘要

A sulfur-vulcanizable rubber compound having high modulus and low hysteresis properties. Such compounds comprise from about 0 to 65 parts by weight of polyisoprene; from about 25 to 35 parts by weight of a high styrene resin, SBR masterbatch and from about 0 to 65 parts by weight of polybutadiene to total 100 parts by weight; from about 50 to 60 parts by weight of a reinforcing filler, per 100 parts by weight of rubber and at least 5 parts by weight of sulfur, per 100 parts by weight of rubber. Pneumatic tires and components therefor are manufactured from rubber compounds having high modulus and low hysteresis and provide run flat operation.
