Formula Optimization to Improve Tire Crown Discoloration
Based on the tread crown compound formula of tires in production,the plasticizer system,protective system and vulcanization system were optimized to improve the discoloration of the tread crown.The results showed that,with comparable compound properties,appropriately reducing the amount of easily migrating small molecule components such as antioxidants in the formula could greatly reduce mold contamination and significantly reduce tire crown discoloration.
