Our company is the main manufacturer of NPCC (nano-precipitated carboante) in China. The particle size of NPCC is about 15-40nm. 60-100nm, it can be widely used in PVCPPPE plastic, rubber, papermaking, offset ink, adhesives and so on.

We are offering nano calcium carbonate. Because of npcc-101 (nano calcium carbonate) nanometer size effect, large specific surface area, surface atoms at a high activation state and the interface with the polymer has a high interaction, when added to paint, it cam be get any special modified paint’s function. Good thixotropy of npcc, its can be used in chassis rock attack paint and face paint. The car is in moving process, the vehicle and wheel fenders, etc. Often were impacted and scoured by sand, grave and son, thus the coating sprayed on the substrate easily damaged, while loss corrosion resistance, the substrate will soon corrosion wear bad. To solve this problem, you can to spray anti-shock and anti-corrosion coating on it . Pvc plastisol is one kind of chasis paint, mainly constituted by the pvc paste resin, plasticizer, filler (nano-precipitated calcium carbonate), stabilizing agent, tackifier, solvent and other additives composition. The amount of npcc is approximately 30% (specific amount of formula should be based), while the addition of npcc to normal, npcc will be larger than the average degree of improvement of rheological properties and film impact resistance. In the process of spray paint, chassis paint should be required to achieve easy to spray, low viscosity, fluidity and viscosity after construction requirements to prevent stick down and sagging. This requires coating at high shear rate, the viscosities were lowered, you can easily spray leveling, in low shear speed or stationary state with high viscosity to prevent coating sink to the bottom and sagging. This property of paint is called thixotropy and npcc in construction performance, structural performance can satisfy this requirement. The nanometer calcium carbonate for chassis paint (pvc plastisol) has the following characteristics: 1. With a high degree of activation. 2. With high yield stress. 3. With good thixotropy.

We are offering Nano Precipitated Calcium Carbonate for Paermaking and Paint (water Soluble). FOR PAPERMAKING: Because NPCC has low oil absorption, fine and uniform particles, good dispersion, high whiteness, low hardness, small and non-toxic wear, odorless, tasteless, and good dispersion etc., in the paper industry, NPCC can increase the brightness of paper, solid structure, profit writing, coating uniformity, low friction, easy to dehumidification and drying easier. As the world’s paper industry from the early 80s last century, the successful shift from acidic to alkaline process technology material used to fill a revolution in change: NPCC and other pigments instead of wood pulp can improve the brightness of paper not permeability, porosity, bulk density, etc.. At present, paper formulations increase the use of NPCC from 5%-10% to 30%. NPCC can be widely used in high-grade paper products. Advantage: 1. Have high opacity and high brightness, can increase the whiteness and opacity of paper. 2. Enable the mill to use more filler and less pulp, can greatly reduce production costs. 3. Fine grain size and uniform of NPCC, wear on the machine is small, and the production of paper products can be more uniform, smooth. 4. High oil absorption of NPCC, can improve the color fastness of color paper. 5. Fill up the neutral paper or cardboard, can improve the tightness of paper or paperboard. Therefore, NPCC for paper fillers have higher bulk density, good plasticity and softness, delicate surface of paper, can significantly improve the performance of paper, so papermaking enterprises to obtain significant economic benefits.

We are offering nano precipitated calcium carbonate for pvc profile applications. Npcc-202 is based on nano precipitated calcium carbonate (npcc) and especially designed for pvc profile application. It is coated by a very special coupling agent with super coupling performance, and internal and external lubricating properties in the extrusion process have been taken into consideration. For ordinary coupling agent there are only about 4-6 coordination bonds, while our special compound agent has as many as 12-16 coordination bonds, hence outstanding plasticizaion property; central atom can connect with electronegativity of atom (for example, -cl on pvc segment), so pvc profile mechanical properties are increased and pvc heat stability is improved，with best rheology and good processibility. characteristics: 1. With big dosage added, mechanical preoperties can be maintained. In pvc profiles, with 20-30 phr added, properties of profiles can meet standard or even better 2. Welding strength can be increased. With best drop hammer in clod temperature and clod stamping, and can improve the surface gloss. 3. Lubricants may be decreased. With npcc-202 added, if there is decrease in voltage, reducing lubricant dosage is recommended; processing aid dosage can be decreased to some extent. 4. With npcc-202 added, it is much easier to control extrusion process 5. Surface quality can be improved, and there is plate out effect 6. In general, the adding quantity of npcc-202 is 8-12%. In processing, if the electric current of the device decreases or reduces, please decrease the amount of lubricant inside and outside 14. And it can significantly reduce production costs also. 7. In abroad, the adding quantity of npcc-202 is 5%. And please also decrease the amount of lubricant inside and outside. specifications npcc-202 specs appearance white powder true density gcm3 2.5-2.6 bulk density gml 0.68 whiteness % ≥95 average size nm 60-100 shape cube ph (10g in 90ml water 8.0-10.0 moisture % ≤0.5 caco3 content (on dry basis) % ≥94.5 activitation % ≥95

We are offering Nano Precipitated Calcium Carbonate for Modified Asphalt. Asphalt is a kind of complicated high molecular hydrocarbons, road paved with asphalt is seamless and continuous, but under high temperature and ultra-violet aging problem will occur. So modifier needed is mainly for the purpose to improve road conditions uder different temperatures. With the increasing of traffic, there has been higher and higher requirements on road. Normal asphalt is very fragile in low temperature and too soft in high temperature, deformation, movement and wheel tracking will occur under busy traffic, so it is difficult for road to function as expected. To solve those problems, asphalt modified with nano calcium carbonate is the solution, and properties, like resistance to high temperature, anti slippy, and wear resistance, durability, and heavy load can be achieved. Characteristics of modified asphalt: 1. Resistance to high and low temperature, effectively increase elasticity and flexibility, cracking resistance under low temperature can be realized. 2. High in flexibility, anti-fatigue, and increase in road load, hence avoid road deformation, and anti-cracking under low temperature. 3. Water-proof, anti-oil and UV, hence effectively prolong aging problem. 4. Stable in property, long duration and low maintenance cost. 5. Reduce asphalt cost greatly.
