"Light calcium carbonate for plastics, rubber, coatings, adhesives" details
Calcium carbonate is an inorganic compound, commonly known as: limestone, limestone, stone powder, marble, etc. Main ingredient: calcite, chemical formula is CaCO? , Neutral, basically insoluble in water, soluble in . It is a common substance on the earth and exists in aragonite, calcite, chalk, limestone, marble, travertine and other rocks, and is also the main component of animal bones or shells. Calcium carbonate is an important building material and is widely used in industry. Calcium carbonate is formed by the combination of calcium ions and carbonate ions, so it is both calcium and carbonate
Application of light calcium carbonate in rubber
Application range: natural rubber, nitrile, styrene-butadiene, compound rubber, etc., suitable for tires, hoses, tapes, oil seals, auto parts and other rubber products.
Application characteristics: The nano-calcium carbonate after surface modification treatment has good compatibility with rubber. It is easy to disperse, the rubber is soft and the rubber surface is smooth after mixing; it can substantially improve the elongation, tensile strength and tear strength of the product; it can reduce the rubber content or partially replace the price of titanium dioxide, white carbon black, etc. Expensive white filler to improve the market competitiveness of products.
The rubber industry is one of the main application markets for light calcium carbonate. The rubber added with light calcium carbonate has higher vulcanizate growth rate, tearing performance, compression deformation and flexure resistance than that with general calcium carbonate. After adding nano-calcium carbonate treated with resin acid, the tear strength of some Yujiao products is increased by more than 4 times.
