Magnesium carbonate CAS NO.546-93-0

1. Mainly used as a filler and reinforcing agent for transparent or light-colored rubber products, and can enhance the wear resistance, bending resistance and tensile strength of rubber. It can also be used as an additive in paints, graphite and coatings, and in industries such as toothpaste, medicine and cosmetics.

2. Flour treatment agent, gum sugar base agent, alkaline agent, desiccant, color protection agent, anti-coagulation agent, bulking agent and acidity regulator. Can be used for table salt, powdered sugar, acidified cream, milk, ice cream, biscuits. China stipulates that it can be used as a flour treatment agent, and the maximum usage is 5.0g/kg; Maximum use in flour is 1.5g/kg.

3. Used for magnesium salt preparation, pharmaceutical industry and filtration of clarified liquids. Used as thermal insulation materials, rubber and special glass ingredients.

4. It is an excellent filler and reinforcing agent for rubber products, and the reinforcing effect is better than calcium carbonate and clay. Its refractive index is similar to natural rubber, so it is suitable for the manufacture of transparent or translucent products, such as tape, rubber wire, sports hygiene products, tape, hose and so on. Used in neoprene adhesives can replace light magnesium oxide, improve the transparency of the adhesive. It is also used in the manufacture of magnesium salt, magnesium oxide, fireproof paint, ink, ceramics, glass, toothpaste, talcum powder, shaving cream, etc. It is used medically as an antacid. Also commonly used as desiccant, filter medium, anti-caking agent and heat insulation, high temperature resistance and fire insulation materials.
