Light Magnesium Carbonate is made of magnesium oxide by special carbonization process.

As a transparent rubber filler with basic magnesium Carbonate, its performance depends on the chemical purity, and rubber with the processing of the degree of difficulty, adding sulfur rubber with color and transparency and enhance the effect. These features are often affected by particle size of magnesium carbonate, the proportion of false, converted to the content of magnesium oxide, developed degree of the crystal structure and physical properties such as refractive index dominated, and the physical properties and restricted by conversion of magnesium carbonate crystallization properties and its shape before, our special process, also becomes the indispensable conditions for making quality rubber filler.

With the rapid development of China’s industry and the improvement of people’s living standards, there is a growing demand for various light-colored rubber products and daily necessities, and light magnesium carbonate has become one of the important pigments in the industry. The properties of light magnesium carbonate are obviously different from other magnesium carbonate. Because its refractive index is close to that of rubber, the light color rubber products mixed with light magnesium carbonate have better transparency, bright color, and have good reinforcement and filling function, which is the ideal filler for making semi-transparent color rubber products.

Light magnesium carbonate, molecular formula 4MgCO3•Mg(OH)2•4H2O, relative molecular weight 467.64, is white amorphous powder, and its chemical composition is a composite of magnesium carbonate and magnesium hydroxide, which is stable in air. The molecular formula varies slightly with the production conditions. Slightly soluble in water, slightly alkaline, easily soluble in dilute acid, when acid foaming decomposition release carbon dioxide, calcining can be decomposed into magnesium oxide and carbon dioxide.

Light magnesium carbonate is mainly used as filler and reinforcing agent for transparent or light-colored rubber products. It hardly changes the refractive index of rubber itself after mixing with rubber, and can enhance the abrasion resistance, flexural resistance and tensile strength of rubber. Mainly used in paints, inks and coatings additives, also widely used in toothpaste, medicine and cosmetics industries.

Meishen Technology Co.,LTD. is a professional manufacturer of magnesium carbonate in China, established in September, 2003. Now we have the brands of MeiShen, XingMei, MeiTai. Products sell well all over the country, including Europe, America, Japan, Australia, South America, South Africa and southeast Asia.
