Nano calcium carbonate for PVC
1.Excellent fluidity: in the plasticizing process of PVC products, the whole process improves the flow performance, the mixture is easy to stir, and at the same time changes the processing performance, reduces the shrinkage rate of products, improves the surface flatness, and makes the products more resistant to yellowing.
2.Improve the surface gloss performance: because it can be well mixed with PVC, can improve the surface gloss of the product, in the thin film type PVC products tear strength is good, low density.
3.Excellent nanometer properties: due to its nanometer properties, its surface is active. It can decompose free moving negatively charged electrons under sunlight and ultraviolet radiation, while leaving positive holes. It is highly active and can easily react with oxygen or organic compounds to improve its anti-aging properties.
4.Mature application practice: it can be widely added in PVC soft products and hard plastic products. It is a mature filling product through the accumulation of a large number of customers.
