Active light calcium in plastic due to low oil absorption value, beneficial to reduce costly plasticizer dosage; Liquidity is good, surface lubrication, easy dispersion, easy mixing, effectively improve the processing properties of plastic products.; The characteristic of high whiteness and color is strong, make plastic products surface is smooth and shiny. ; Beneficial to improve the stability of the plastic product size and its heat resistance, making it not only has good hardness and rigidity, and better strength and elongation. Active light calcium the product specific surface area, oil absorption value is higher, the rubber has good invasive; Vulcanized rubber performance can be improved efficiently, not only can improve the hardness, wear resistance of rubber products, and can improve the bending strength, impact strength; Rheological properties is good, easy dispersion, easy mixing, rubber products processing performance can be improved efficiently; Can effectively increase the volume of the rubber products, improve its heat resistance; Beneficial to improve insulation rubber products, and can make the rubber surface gloss. Active light calcium with good affinity and dispersion in the coatings industry; A strong cover rate, good permeability, antirust function; High whiteness, good tinctorial yield; Has good adhesion and inhibiting coating peeling; Low oil absorption value, PH = 7-8
