Suoyi High quality CaCO3 Calcium Carbonate for Plastic & Rubber
Calcium carbonate is an inorganic compound with the chemical formula CaCO3, and is the main component of limestone, marble, etc. Calcium carbonate is usually white crystals, odorless, and essentially insoluble in water. It is one of the common substances found on earth within rocks such as aragonite, calcite, chalk, limestone, marble, travertine, etc. It is also a major component of the bones or shells of some animals. Calcium carbonate is also an important building material with a wide range of industrial uses.
Calcium carbonate has a crystalline structure, high whiteness, fine particle size and reasonable particle size distribution. It is used as a filler in papermaking, which can give the paper a good whiteness and bulk, make the paper smooth and soft, and feel good.
Calcium carbonate has a high birefringence, high refractive index, and high scattering coefficient, which can make the paper opaque; calcium carbonate has good ink absorption properties, so that the printing ink solidifies quickly, so that the paper meets the requirements of high-speed rotary printing ; the particle size of calcium carbonate is small, the specific surface area is large, the filler retention rate is large, and the sizing degree and strength of the finished paper are not lost.
1. Rubber industry: calcium carbonate is one of the largest fillers used in rubber industry.
2. Plastic industry: calcium carbonate can play a skeleton role in plastic products,
3. Paint industry: the consumption of calcium carbonate in the paint industry is also large, for example, the consumption in the thick paint is more than 30%.
4. coating industry: it can make the coating not settle, easy to disperse, good luster and other characteristics, and the amount of water-based coating is 20-60%.
5. Paper industry: can ensure the strength and whiteness of paper, and low cost. In the cable industry products, can play a certain role in insulation.
6. Adhesives and sealants: widely used.
