1. Granule size for Calcium Carbonate:  ≤4μm
2. Whiteness : ≥98%
3. Application ratio: Mix Nano Filler MB with the stuff   resin from the ratio of 10% to more than 30% (different ratio decided by the product and user).

Compare to normal filler MB, Nano filler MB is with below superiority:
1. Remain anti-impulsion property and flexibility of plastic  material. Even when the application ratio is high,it will not reduce the physical and mechanical property of plastic products much.
2. Nano Filler MB is with good dispersing quality to assure the smooth appearance of plastic products, so that it can guarantee good printing quality of surface for first and mid grade plastic products.
3. When some inorganic materials of nanometer frame are  introduced, the bad effect of material aging property is distinctly reduced.
4. Under same ratio condition, Nano filler MB can distinctly
    improve the transparency of plastic products.
