What are the advantages of magnesium carbonate as rubber filler？

Magnesium carbonate is also an important filler among tire products, and because magnesium sulfate has a very significant effect on the density of rubber. In general, for dynamic use of rubber products, such as tires, etc., the greater the mass, then the heat generated in the movement process, the greater the resistance, therefore, the consumption of rubber products faster, the service life will be shorter. Many foreign brand-name tires its magnesium carbonate dosage is much lower than the domestic common level, generally about 2-3 parts. Magnesium carbonate in the amount of 30% -70% after the rubber tire heat, aging and other aspects of the performance did not occur larger changes, but the degree of its abrasion reduction is significantly better than the normal amount of magnesium carbonate tires, and magnesium carbonate after the reduction of the tire density has a significant reduction in not only effectively reduce the cost of the rubber material and the quality of the rubber material, but also to a great extent to improve the use of rubber material performance.
