50% of industrially produced zinc oxide goes to the rubber industry. Zinc oxide and stearic acid, as important reactants for rubber vulcanization, are one of the raw materials for rubber manufacturing. The combination of zinc oxide and stearic acid enhances the hardness of the rubber. Zinc oxide is also an important additive for car tires. In addition to vulcanization, zinc oxide can greatly improve the thermal conductivity of rubber, thereby contributing to the heat dissipation of tires and ensuring driving safety. The zinc oxide additive also prevents the attack of mold organisms or UV light on the rubber.
The role of zinc oxide in silicone rubber is mainly to act as a crosslinking accelerator, and at the same time, it has a reinforcing effect. Zinc oxide can accelerate the vulcanization reaction in the early stage of vulcanization of silicone rubber, and delay the vulcanization reaction in the later stage of vulcanization, which can improve its minimum torque and maximum torque. At the same time, the hardness of the vulcanizate will also increase, and the tensile strength will also increase.
increase. Zinc oxide can also improve temperature resistance. Compared with zinc oxide, the functions of zinc carbonate and zinc oxide are roughly the same, but the appearance of the products made is relatively transparent.
