Abstract:
Rubber blends of SBR and EPDM having improved dynamic ozone resistance, heat resistance, and flex fatigue resistance can be made by co-curing such rubber blends with a sulfur donor/accelerator and a peroxide curing agent. In some aspects, these blends are void of free sulfur. These cured rubber formulations can advantageously be used in a wide variety of industrial rubber products, such as in conveyor belts. The disclosure also reveals conveyor belts which have a combination of good dynamic ozone resistance, heat resistance, and flex fatigue resistance. The conveyor belt include a carry cover layer, a pulley cover layer, and a reinforcement layer which is situated between the carry cover layer and the pulley cover layer, and the carry cover layer and/or the pulley cover layer contain cured rubber formulations according to the disclosure.

Claim (Index 12):
A method of curing a rubber formulation which is comprised of about 45 phr to about 75 phr of styrene-butadiene rubber and about 25 phr to about 50 phr of an ethylene-propylene-diene monomer rubber to provide cured rubber formulation with a combination of good dynamic ozone resistance, heat resistance, and flex fatigue resistance, said method comprising curing the rubber formulation with a curative system which includes about 1.8 phr to 3.6 phr of a sulfur donor/accelerator, and about 0.2 phr to 2.0 phr of a peroxide curing agent.
