sell : coated calcium carbonate

Specifications: Appearance: white powder CaCO3,% ≥ 98.28 PH 9.67 105oC Volatile,% ≤ 0.24 Average grain size,μm ≤ 1.95 Sieve residue 325 mesh(%) None Brightness(R457,powder),% ≥ 95.3 Activity, % ≥ 99 Subsidence Value ml/g ≥ 2.6 Oil absorption number (DOP),ml/100g ≤ 35 2)Advantage: can be well dispersed in the basic materials of wires and cables as the isolated filler. It can make a product that successfully rivals steel and aluminum, improve the processability characteristics of the products, enhance the surface gloss and many physical properties of the compound, and increase the effective addition. The role of calcium carbonate in wire and cable is to strength to the polymer, lower the cost of the finished product and improve the processability characteristics of the products. 2) This product is a fine precipitated calcium carbonate with its fine and uniform particle size, special surface activity as well; it can be well dispersed in the basic materials. The active of product is not less than 98%
