Nano calcium carbonate for plastic SPSL series of nano and submicron calcium carbonate can be used for injection molding, general extrusion, injection molding, etc., not only for modified PVC, PP modified, PE modification, ABS modified, PS modified , can also be used UPVC plastic building materials, wire and cable, FRP and other fields. SPSL products can increase the material stiffness, toughness, bending strength; even under the high filler content can increase by several times toughness; its surface activation, good compatibility with resin, melt strength and the product size and stability, can improve product surface finish; can replace part of the fill materials and expensive modifier to reduce the amount of resin, thus reducing product costs and enhance market competitiveness. 
 SPSL project indicators: average a particle size (nm) 60-90 100-300: calcium carbonate content (%)> 98: oil absorption value (gDOP/100gCaCO 3) <27: specific surface area (m 2 / g) 23 ± 4 11 ± 4: morphology of cubic cubic, prismatic hydrochloric acid insoluble (%) <0.1: Moisture (%) <0.3: Special treatment agent treatment agent: crystalline calcite: acidity (pH) 8.5 - 10: whiteness (%)> 97 :
