Can black masterbatch containing calcium carbonate be used?

08/24/2018

To be comprehensive. First of all, if the calcium carbonate has a fineness of 1000 mesh and a content of less than 10% in the black masterbatch, it is a good choice for products that are not required for outdoor exposure, and the price is low. The appearance of the product is good, the carbon black is uniformly dispersed during processing, the blackness is not affected, and the influence on the product strength is small.

If the fineness of the calcium carbonate is less than 1000 mesh, the gloss may be dim, the surface may be rough, and the strength of the product may be lowered. If the amount of 1000-million calcium carbonate exceeds 10%, the surface of the product is dull and gray, and the blackness is insufficient, and the strength of the product is lowered. Secondly, in any outdoor products with anti-aging requirements, it is not good to contain calcium carbonate, depending on the service life of the product.
