Effects of calcium carbonate on the properties of plastic

 · At present the whiteness of calcium carbonate for 400 purposes is required to reach more than 95 and the whiteness of calcium carbonate processed by some ores can reach about 97 . In order to improve the whiteness of products some modified masterbatch manufacturers often add fluorescent whitener to achieve the effect of increasing whiteness.
