Study on the Long-Term Aging-Resistance of Anti-Vibration Rubber in the Vehicle 2002-01-0725

Anti-vibration rubbers in vehicle play an important role in restricting vibration generated from engine and road. But, degradation occurs when rubber is exposed for a long time to heat, light, ozone and etc. These make the rubber hard and lose its initial properties. The rubber change makes N.V.H performance of vehicle the worse, and gives the discomfort to the passengers. To reduce the change of rubber properties, sulfur-donor and heat stable cross-linking co-agent vulcanization system have been introduced in the developed natural rubber compounds of the anti-vibration rubber parts. These lead to a reduction of degradation of material properties, maintenance of the initial properties and increase of the fatigue life.
