precipitated calcium carbonate in industry
1.useage: Paint, Dope, Rubber, PVC pipe, Paper making etc as stuff materials
2.manufacture process:burn the limstone so create the calcium oxide then mix the water,create the Calcium hydroxide,then through carbonize,dehydrate,dry and smash.

4.packing:25kg per composite woven bags or as your need.
5.advantage: make products have good formed effect and enhance hardness, rigidity, size stablity, and glossiness of products.
6.Main application:
Fillers of plastic such as for plastic,rubber,paper,polyvinyl chloride(PVC).
Polyethylene(PE),polypropylene(PP),ABS,etc.
It is widely used as filler in making rubber,plastic,paper,paint,printing etc.
