BaiRui precipitated calcium carbonate powder is high whitness , high oil absorption , high settling volume .
BaiRui own Three factory for precipiated calicum carbonate powder ,one for paint clients, another one for plastic and rubber clients , the third one for pvc pipe clients.
Precipiated calcium carbonate powder export to Indonesia, Thailand, Bangladesh,Philippines,Dubai,Afghan,India countries ect.
Applications and advantages:
| Rubber | it can reduce the amount of expensive natural rubber,increase its volume ,reduce costs, After adding calcium carbonate then can be obtain higher strength tensile ,tear strength and abrasion resistance than the pure Rubber vulcanizate |
| Painting& coating |
it is as the filling and as the framework, Latex paint more than 30% amount are used in thick paint ,26%-60% amount are used in water-based pain |
| Plastic | it can increase the volume of plastics, reduce the costs, improve the size, stability, hardness and tenacity of plastic products. |
| Paperpulp material | it can fully make use of its high whiteness, affinity to water and shock intensity, low cost widely using . |
| Chemical manufacturing materials | it is heat-proof, chemical corrosion-proof,cold-proof, anti-noise, shockproof and easy to process. Therefore it can be used to make doors, dry motar ,ceilings, wallboard,waterpipe,handrail of stairs,floor board and electric wire,etc. |
