Main Applications of Our Carbon Black

Our color carbon blacks are used in a variety of common and specialty products, including:
Printing inks: Our carbon blacks can be used in Printing inks, for example, the Offset Thermosetting Rotary Ink, Intaglio,Liquid Ink, Water Flexo Plate Ink, Water Ink Used in News Printing, Solvent Ink Used in News Printing and etc. 
Plastics: Our carbon blacks are widely used in plastic products such as PVC, ABS, LDPE/HDPE, PP, NYLON, PC, PU and etc.
Leathers: Our carbon can also be used in Leathers, enjoying high blackness, dispersity,dispersal Viscosity.
Painting and Coatings: Our carbon blacks  has excellent performance in painting and coatings, for example, high blackness surface paint used in vehicle and furniture, high blackness paint used in industry, varieties of prime paint, powder ocating and etc.

1.Several typical parameters of carbon black

* Blackness(reflectivity)---Blackness of carbon black is commonly represented by data measured by ‘reflectivity tester’, it also reflects the primary particle size of carbon black in most cases. It is one of the important parameters to evaluate the market price of carbon black. The lower reflectivity, the higher blackness of carbon black, the smaller particle size is. Same on the contrary.

* Structure---Structure of carbon black is typical value of chain index formed by carbon black micro particle aggregate. It expresses the space level within carbon black. It is represented by adsorption(DBP adsorption).

* Volatile content---the quantity of oxygenous group on the surface of carbon black reflects the physical performance electro--chemical performance and application performance of the surface of carbon black, and it’s also the one of the important parameters to evaluate price on the carbon black market.

2.The basic thinking of selecting CB

Before selecting CB, the first thing users must take into account is what purpose you want to achieve by using CB, tinting, color matching, uvioresistant or using for electro--conductive carbon? The most important point is to communicate with CB professional engineers and make a technology assessment of material system together, then select suitable CB for yourself.

Normal situation is:

* Tinting----high blackness, small particle size CB is suggested. But they must be dispersed perfectly at the same time, otherwise, you will run in the opposite direction and never come to the goal.

* Color matching----low blackness, large particle size, good dispersion CB is suggested.

* Uvioresistant---the main use is in plastic and rubber, the CB that has middle particle size and a little high structure is suggested, because it has the best uvioresistant performance.

◎—Excellent performance ○—Good performance

The basic demands of CB used in ink: high tinting strength, high fluidness, high gloss, blue color shade, low impurity content, usually the CB that has lower oil adsorptive capacity can be selected. If there is no special requirement for blackness of CB, the CB that has large particle size can be selected.

◎—Excellent performance ○—Good performance

The demands of CB used in plastic high purity, excellent strength, good dispersivity.

If used for tinting and requiring high brightness, small particle size and low structure CB can be selected.

If used for color matching and requiring good dispersion, large particle size and high structure CB can be selected.

If requiring uvioresistant, the CB those particle size are between 18 and 22 nm can be selected.
