Main ingredients: Calcium carbonate, chemical formula CaCO3
Features:
Nano calcium carbonate is also called ultrafine calcium carbonate. The most mature application of nano-calcium carbonate is the plastics industry, which is mainly used in high-end plastic products. It can improve the rheology of the plastic masterbatch and improve its moldability. Used as a plastic filler, it has the function of toughening and strengthening, improving the bending strength and bending elastic modulus of the plastic, thermal deformation temperature and dimensional stability, and also giving the plastic heat hysteresis. Nano calcium carbonate used in ink products shows excellent dispersibility and transparency, excellent gloss, and excellent ink absorption and high dryness. Nano calcium carbonate is used as an ink filler in resin-based inks, which has the advantages of good stability, high gloss, not affecting the drying performance of printing inks, and strong adaptability.
