Superfine Calcium Carbonate

DIACAL CC is a ultra-fine calcium carbonate which has 60 nm of primary particle size. These particles are surface coated with fatty acids in order to improve dispersion property at the mixing stage with organic materials. DIACAL CC will enhance the mechanical strength of polymer and other organic materials when used.

For DIACAL CC series, two different specifications are available as below.

Usage of DIACAL CC in tyres
DIACAL CC surface treated with fatty acids, has the ability to mix evenly into the rubber matrix, allowing high loadings with fillers bounded tightly. Rubber matrix loaded with DIACAL CC nano calcium carbonate, exhibits better rubber-filler interactions, the particles aid in bounding the rubber therefore is able to reinforce the tyres manufactured.


Usage of DIACAL CC in resistance bands
DIACAL CC is of nano-grade, which has much higher surface area compared to other micro grade calcium carbonate. DIACAL CC nano calcium carbonate have higher surface area, therefore is able to better contact with the rubber matrix, thus increasing tensile strength and tear resistance of rubber products.
