Description:
Baizheng offer high quality Ground calcium carbonate which is a natural form of calcium carbonate that is available in controlled particle size to give improved results to the end products. Our calcite powder is widely used as filler due to its various striking features such as:
* High dispersibility
* Low oil absorption
* Higher impact strength
* Smooth surface finish
* Easy processing
* Excellent dimensional stability
This is used in different industries which includes:
* Plastics
* Paints
* Rubber
Further, Baizheng Ground calcium carbonate leaves various effects on properties of polymers such as:
* Increase in flexural modulus
* Increase in dimensional stability reduces creep resistance
* Increase in HDT
* Lowers melt viscosity
* Improved electrical properties
* Improved processing characteristics
* Good dispersion
* Excellent hiding power
This is widely used in different applications which includes:
* PP compounding for furniture, automobiles & home appliances
* Antifabrilliant master woven sack batches for PP & LDPE
* PVC cable compounding
* Paints
* Paper coatings
* Thermoset plastic
* Vinyl floorings
* PU foam (flexible & rigid)
* Powder coatings.
