What's the difference between the black, the black sand and the carbon black

It is generally known that the black parent is made of black carrier, PP (PE), carbon black and other compatible additives. The content of carbon black is not high and the amount of addition is relatively large, but because of its good compatibility with plastics, it is widely used. Black sand is usually made from plasticizers plus carbon black, with less added capacity and better anxiety than black ones. Carbon black itself is the strongest coloring power, but the premise is good dispersion, because it is easy to cause the production site dirty, so the use is limited.
