The tire reclaimed rubber processed from waste tire rubber powder has low price and good physical and mechanical properties. Its main components are natural rubber, synthetic rubber and carbon black. It has good compatibility with natural rubber and can replace part of natural rubber to produce various types of natural rubber. Products can effectively reduce the cost of raw materials on the premise of ensuring quality. In actual production, 100 parts of tire reclaimed rubber 2ELYY817 can be used instead of about 30 parts of raw rubber. Other components in reclaimed rubber can be regarded as softeners and fillers. Therefore, active agents and antioxidants in the formulation of natural rubber products mixed with reclaimed rubber , fillers, softeners and other dosages need to be appropriately reduced.
