Calcium carbonate in a large number of plastic use, the plastic industry is not highly valued by chance, compared to other non-metallic mineral powder material, calcium carbonate has obvious advantages.
1) the price is cheap
Both heavy and light calcium carbonate in various non mineral powder is the price reasonable. That is to say, any a kind of non mineral powder just trying to to replace the calcium carbonate as the plastic filling material, and features than the salience of the powder material itself, it is meaningless.
