calcium carbonate powder 7000 mesh

 Features and Applications

calcium carbonate powder 7000 mesh, has the following advantages:
1, excellent mobility: in plasticized PVC products process, full improve flow properties, mixture mixing easily, also changes the performance of machining, such as reducing shrinkage rate, improve the surface roughness, make the products more resistance to yellowing.
2, improve the surface gloss: due to the PVC can be a very good mix, can improve the surface gloss of the product, in the film PVC products in the anti tear strength is good, the density is small.
3. Excellent nano characteristics: due to the nanoscale properties, its surface is active, in the sunlight, ultraviolet radiation can decomposition of negatively charged electrons move freely, while leaving the positively charged holes, with strong activity, easily with oxygen or organic chemical reaction, improve the resistance to ageing.
4, mature application practice: can be in PVC soft products, hard plastic products in a large number of add, through a large number of customer accumulation, is a mature filling products. "
