PCC 1500 mesh

PCC 1500 1.Calcium Carbonate 98%min 2.Whiteness 97%min 3.pure white powder

precipitated calcium carbonate

Molecular Formula: CaCO3

Appearance: White Powder

CAS No.: 471-34-1

EINECS No.: 207-439-9

Usage:

1.in plastic industry:It can improve the stability of the size of plastic products, improve the hardness, heat resistance .

2.In rubber industry: As the filler, It can rise to add volume, reduce the cost, improve the processing properties and vulcanization performance.

3.In paper industry: can be used as paper filler and white pigment.

4.In painting industry: It can replace the other expensive filler to reduce the cost.

Manufacture:

Burn the limestone to create the calcium oxide then mix the water, create the Calcium hydroxide, then through carbonize, dehydrate, dry and smash.
