DiamondDiamond Nano-Biochem. Co., Ltd. Nano-Biochem. Co., Ltd. supplies a superfine calcium carbonate filler specifically formulated for rubber compounds, marketed as DIACAL‑CC. The material is precipitated calcium carbonate (CaCO3) with a reported purity above 98 % and particle dimensions in the sub‑micron range. Produced in Taiwan, the powder carries a fatty surface coating that enhances dispersibility during mixing. It is supplied in bulk packaging suitable for industrial compounding operations.
In the rubber industry, superfine calcium carbonate is valued for its ability to reinforce and reduce cost compared with silica fillers. Typical industry grades exhibit bulk densities around 0.5 g cm‑3 and moisture contents below 0.2 %, which align with the supplier’s product class. The fatty coating is a standard treatment to improve wetting and compatibility with polymer matrices. Standard specifications also include a pH of about 9.5 in aqueous suspension and a D90 particle size near 1 µm, matching the sub‑micron claim.
Manufacturers of tires, conveyor belts and automotive rubber components commonly source this filler to achieve targeted mechanical properties. Trade terms often involve flexible minimum order quantities and FOB pricing, with payment typically arranged via T/T. Buyers should confirm packaging size - usually 25 kg bags or bulk containers - and request ISO or SGS certificates before shipment.
