functional can stable the whiteness , lower the oil absorption , increase the glossy and enhance tensile strength .

Compound powder (Functional calcium carbonate )

Compund powder also named Functional Calcium Carbonate , this product contain

Calcium carbonate abt 98%, whithness is abt 98% , particle size 1.2 um , the manufacturing process is the chemical coated . enable the product have the advantage of have good dispersibility, lower oil absorption , high glossy , strengthen tensil when it be used in the plastic , paint and powder coating industry .

Especially when it be used in PVC industry , the compound powder and the light calcium carbonate usage ratio according to the formulat rate 1:1 , will get the better result. Because the light calcium carbonate oil absorption is bigger , and the whiteness is not so stable and the glossy is lower . the compound powder be used together with the light calcium carbonate , can make up the disadvantage of the light calcium carbonate . can stable the whiteness , lower the oil absorption , increase the glossy and enhance tensile strength .
