Messi Biology Transparent Lightweight Magnesium Carbonate Properties and Applications

With the rapid development of my country\’s industry and the improvement of people\’s living standards, the demand for various light-colored rubber products and daily necessities is increasing, and transparent light magnesium carbonate has become one of the important pigments in the industry. Transparent light magnesium carbonate, molecular formula 4MgCO3•Mg(OH)2•4H2O, relative molecular weight 467.64, is a white amorphous powder, its chemical composition is a composite of magnesium carbonate and magnesium hydroxide, relatively stable in the air. Its molecular formula varies slightly with changes in production conditions. Slightly soluble in water, weakly alkaline, easily soluble in dilute acid, foams and decomposes in acid to release carbon dioxide, can be decomposed into magnesium oxide and carbon dioxide when heated and calcined.

The properties of Hebei Messi Biology Co., Ltd. transparent light magnesium carbonate are obviously different from other brands of magnesium carbonate. Because the refractive index is close to that of rubber, the light-colored rubber products made by adding Messi Biology Transparent Light Magnesium Carbonate have better transparency, bright coloring, and good reinforcement and filling effects. Ideal filler for rubber products.

production method

Hebei Messi Biology Co., Ltd. transparent light magnesium carbonate is made of hydromagnesite as raw material and carbonized by special process. The performance of basic magnesium carbonate used as a transparent rubber filler depends on the chemical purity, the ease of processing when it is mixed with rubber, the color tone and transparency of the vulcanized rubber when it is mixed, and the reinforcing effect. These properties are often dominated by physical properties such as particle size, pseudo-gravity, content converted to magnesium oxide, crystal structure development, and refractive index of magnesium carbonate, and these physical properties are limited by the crystallization characteristics and shape of magnesium carbonate before transformation. , our special process has become an indispensable condition for the manufacture of high-quality rubber fillers.


Transparent light magnesium carbonate is mainly used as a filler and reinforcing agent for transparent or light-colored rubber products. After it is mixed with rubber, it hardly changes the refractive index of the rubber itself, and can enhance the wear resistance and flex resistance of the rubber. and tensile strength. It is mainly used as an additive for paints, inks and coatings, and is also widely used in medicine, food, cosmetics and other industries.
