Basic information
Chemical name: nano calcium carbonate, also known as ultra fine calcium carbonate
Chemical formula: CaCO₃
English name: Nano Calcium Carbonate
Product characteristics
Ultra-small particle size: The particle size is usually between 1-100nm and has a finer particle size compared to
ordinary calcium carbonate, giving it unique physical and chemical properties.
Large specific surface area: the specific surface area is generally between 50-200m²/g, and the larger specific surface
area makes the nano-calcium carbonate have higher surface activity and adsorption properties, and can be better
combined with other substances.
High purity: the purity of the product can usually reach more than 95%, and the impurity content is very low, which
ensures the stability and reliability in various application fields and reduces the adverse effects caused by impurities.
Good dispersion: After special surface treatment process, nano-calcium carbonate in different media can show good
dispersion, not easy to agglomerate, can be evenly distributed in the matrix material, give full play to its enhancement,
modification and other roles.
Nano calcium carbonate has many important applications in medical PVC materials
Improve mechanical properties
Enhanced hardness: Medical PVC material in some application scenarios need to have a certain hardness to ensure
the shape and functional stability of the instrument, the addition of nano-calcium carbonate can effectively
improve the hardness of the material. Nanometer calcium carbonate has small particle size and large specific
surface area, and can be closely combined with PVC molecular chain, play the role of physical crosslinking point,
limit the movement of molecular chain, thus increasing the hardness of the material.
Improve toughness: nano-calcium carbonate can improve the toughness of medical PVC materials without
reducing the flexibility of the material. It can be evenly dispersed in the PVC matrix, when the material is impacted
by external forces, nano-calcium carbonate particles can cause the matrix to produce silver stripes and shear
bands, absorb and dissipate the impact energy, so as to improve the impact resistance of the material, so that
medical PVC products are less likely to break during use.
Improve machining performance
Promote plasticization: nano-calcium carbonate can reduce the plasticization temperature of medical PVC
materials, making it easier to plasticize during processing.
Improve fluidity: Nano-calcium carbonate can improve the fluidity of medical PVC materials during processing. It
can play a lubricating and isolating role between the PVC molecular chains, reduce the friction and entanglement
between the molecular chains, make the material flow and fill more easily in the mold, is conducive to the
manufacture of complex shapes of medical PVC products, such as various medical pipe fittings, medical device
shells, etc., can improve the dimensional accuracy and surface quality of the products.
