Problems solved by technology

[0002] Motorcycle engine rubber gaskets are prone to aging due to the combined effects of various external factors, and their properties gradually change, especially unsaturated carbon chain rubber, which is easily attacked by heat, oxygen and ozone, resulting in changes in the molecular structure of the rubber, especially Motorcycle engine rubber gaskets are exposed to high temperature and rugged road conditions for a long time, especially in hot summer environments, the performance of motorcycle engine rubber gaskets drops significantly. At present, motorcycle engine rubber gaskets have thermal stability, hardness, and tear resistance. and aging resistance can not meet the demand
