Natural rubber has high mechanical strength, good elasticity, good insulation, water resistance and plasticity, and is widely used in daily production, medical and health care, transportation, industrial agriculture and other fields. However, from the perspective of the manufacturing cost of natural rubber products, due to the high price of natural rubber and large price fluctuations, many natural rubber product manufacturers have begun to add a certain amount of tire reclaimed rubber to the formula to reduce the amount of natural rubber and reduce production costs.
The editor will continue to share with you the formula of rubber shoe material and rubber tube mixed with tire reclaimed rubber with natural rubber as the main raw material.
