Hebei Messi Biology Co., Ltd. stated that magnesium oxide and zinc oxide in rubber mainly play a role in fluidity and antioxidant capacity, increase the tensile strength and impact resistance of rubber, and magnesium oxide is an important compounding agent for halogen-containing rubber. Activity is an important indicator for measuring magnesium oxide for rubber. As one of the main inorganic active agents, active magnesium oxide can greatly increase the degree of vulcanization when used in a small amount in the rubber compound.
In chloroprene rubber, magnesium oxide and zinc oxide are used as vulcanizers together. Reducing the activity of zinc oxide slows down the vulcanization rate and prevents early cross-linking; at the same time, magnesium oxide acts as an acid acceptor to prevent scorching and cyclization, and is usually added at the beginning of mixing; the activity (iodine adsorption value) of magnesium oxide has a great influence on the anti-scorching performance of CR, and also affects the tensile strength, elongation and hardness of CR. Light magnesium oxide is a common variety. Magnesium oxide is often used in alloy rubber, such as when used in combination with PVC or CM rubber, so that the product will not be under-sulfurized, which is consistent with the mechanism of action of magnesium oxide in halogen-containing rubber. Although magnesium oxide is not an important material in rubber, it also plays a very important role!
Hebei Messi Biology Co., Ltd. is a national high-tech enterprise specializing in the research and development and production of pharmaceutical and food grade, high-purity nano-grade magnesium oxide. The rubber industry is one of the company’s long-term important strategic areas.
