NANO PRECIPITAED CALCIUM CARBONATE (NPCC) NPCC refers to ultra-fine precipitated calcium carbonate with an average particle diameter of less than 100 nanometers that is used as an additive in various products. Because of its special physical and chemical properties, NPCC has been widely applied in the paint, paper, plastic and rubber industries. Advanced technology allows the synthesis of calcium carbonates in nano-particles with large surface area. Each particle is surface coated with modifier such as fatty acid, organic coupling agents, to improve dispersion and compatibility with polymer matrix. NPCC expects to have a potential market as the substituted product for other expensive additives, such as carbon black, white carbon black, and titanium dioxide. While the field of nano particle research has exploded in recent years, nano PCCs have been in commercial use for much longer. This have been widely used to make automotive and construction sealants and PVC window profiles. This ranges from 0.06 microns or 60 nanometers to 0.15 microns or 150 nanometers in median particle size. This is an order of magnitude smaller than the so-called ultrafine ground calcium carbonates, which are typically 0.7 microns. This results in ultrafines that are uniform in shape, size and particle size distribution. These ultrafine PCC particles also act as a semi-reinforcing filler, for strong physical performance. PVC plastisols, urethanes, silicones, polysulfides, and silylated polyethers are some of the types of high performance, long-lived automotive and construction sealants that use nano PCCs.
NPCC FOR PAINTS
Applications:
Auto Paint, PVC Plastisol, underbody sealing materials for automobiles, constructional sealing compounds. The surface-modified nano-size calcium carbonate particles are capable of controlling the rheological and the mechanical properties of the cured Materials. PVC Plastisols with nano calcium carbonate have extended glass transition temperatures (Tg) excellent thermal stability and low viscosity.
Good tensile strength, elongation-at-break and yield stress.
Features: Nano Particle Size, Nano Particle Size Distributon, Regular Particle Shape, Surface Special Treatment.
Benefits: Reduced Volume Formulation Cost, Improved Product Quality. Due to special physical and chemical properties, NPCC has been widely applied in Industries likeNPCC FORADHESIVE & SEALANTS
Applications:
NPCC is a functional additive providing and viscosity, thixtropy, shear thinning and yield value for economical control of slump, sag and extrusion or spray application rates also reinforce the polymers increasing tensile strength and modulus.
Physical properties are improved due to the semi reinforcing performance of NPCC.- with NPCC, viscosity and thixotropy of adhesives & sealants can be adjusted to suit specific application needs.

NPCC FOR PRINTING INKS
Applications:
Functional Nano Calcium Carbonate is a surface treated super ultra fine particle with very narrow particle size distribution. Precipitated calcium carbonate is specially formulated as functional additive in ink.
Ink Industry: includes Solvent Ink, Offset Ink Or Lithographic Inks.
In highly filled litho inks, they can serve as the main rheological additive and cost Reducing filler. In lightly filled offset inks, they can extend other more expensive Thickeners, as well as replace oils and varnishes. It thickens, PVC Plastisol Silk Screen Inks. Gravure Inks need very low abrasion fillers.
Small particle Sized NPCC is excellent here.

The application of an active nano-calcium carbonate in tire was experimentally investigated. The results showed that the processibility of rubber compound and the physical properties of vulcanizate improved by adding 5–8 phr active nano-calcium carbonate in the sidewall and carcass ply compounds of bias ply tire and adjusting the addition level of carbon black and softener properly; the comparable tear strength, abrasion resistance and other physical properties of vulcanizate and the better extrudability were obtained by adding 4 phr active nano-calcium carbonate in the tread compound of radial tire; and the production cost reduced.
8%NPCC in rubber compound greatly improves tire's tear resistance and abrasion resistance.
Because of the better thermal conductivity, heat can dissipate quickly, resulting in less heat build-up during operation.
