Exploring the Potential of Bound Antioxidant Nitrile Rubber in Automotive Applications

Increasing performance requirements have prompted numerous studies to improve the aging of NBR. The Goodyear Tire & Rubber Company has developed a family of polymerization bound antioxidant stabilized CHEMIGUM * rubbers which have superior heat, abrasion, compression set resistance, and persistent non-volatile or extractable antioxidant protection.

These polymers are being evaluated as alternatives to conventional NBR, ECO, PA, silicone and fluorocarbon polymers in applications such as power steering and transmission seals, fuel hose and compressor seals. More costly polymers have previously displaced conventional NBR in some of these applications.

NBR warrants reevaluation due to the current world energy situation where there is a need to apply new technology, and lowest cost polymer systems to their fullest potential.
