Nano calcium carbonate is also called ultra-fine calcium carbonate. The precursor of nano calcium carbonate is non-metallic ore limestone, which is used to synthesize important inorganic salt products through reaction precipitation. The particle size of nanometer sized powder is 0.01~0.1 μ M. As an important inorganic filler, in addition to being widely used, it also has the advantages of high cost performance, no harm, good gloss and high whiteness.
The most mature application industry of nano calcium carbonate is the plastic industry, which is mainly used in high-grade plastic products. It is widely used in rubber, plastics, papermaking, chemical building materials, inks, coatings, sealants and adhesives.
Application: tire, hose, adhesive tape, sealing ring, auto parts and other rubber products.
Features: it has three-dimensional structure, good dispersion and good combination with other fillers.
Functions: reinforcing effect, enhancing stretching, anti-aging, improving performance, reducing cost.
Application: wire drawing, injection molding, bidirectional stretch film, PVC profile, wire, cable outer rubber particles, soft plastic

Advantages of nano calcium
It can improve the rheology of plastic masterbatch and improve its formability. As a plastic filler, it can toughen and strengthen the plastic, improve the bending strength, bending elastic modulus, thermal deformation temperature and dimensional stability of the plastic, and endow the plastic with thermal hysteresis. Nano calcium carbonate used in ink products shows excellent dispersion, transparency, excellent gloss, excellent ink absorption and high dryness. Nano calcium carbonate as ink filler in resin based ink has the advantages of good stability, high gloss, not affecting the drying performance of printing ink, strong adaptability and so on.
