Characteristics of pigment carbon black 
1. The best black pigment.
2. Almost the cheapest pigment.
3. The best tinting strength and hiding power among all kinds of pigments.
4. The most stable pigment with good durability on heat, chemicals and light.
Technical Crafts (Processing Methods) of pigment carbon black 
Generally speaking, the processing methods for Pigment Carbon Blacks globally are Furnace, Touching (including Channel and Gas without channel) and Thermal Decomposition. We are now using furnace method and gas method, which are the most important and conventional crafts currently. 
For Furnace processing, in a hermetic furnace, liquid hydrocarbons (coal tar) are sprayed into burning hot air and natural gas through nozzles, which is oxygenated and decompounded under high temperature; we could control performance of pigment carbon blacks by controlling flame quenching; Then, the pigment carbon black products are separated from the quenched gas steam through filtering system. The character of furnace method is a wide range of choices of its raw materials with various performance of pigment carbon black. From the point of output, Furnace method is the most important producing method of pigment carbon black till now.
Gas method, also refers to gas without channel method, is an improved process from channel method. For channel method, after gasified in a gasification chamber, solid hydrocarbons (crude anthracene) or liquid hydrocarbons (anthracene oil) are mixed with combustive gas (usually natural gas, sometimes coke gas and water gas). As feedstock, they are directed through internal passages located within the wall of the reaction device to the heating room, burned under high temperature in the flame nozzles and collected after cooled down in the cooling side of the device's wall. While the cooling in the heating room without channel steel is called gas method. The carbon blacks obtaining smaller particle size under the improved method by which has relatively lower output than furnace process perform better in blackness and tinting strength. 
We can supply Powder form pigment carbon black and Beads form pigment carbon black to standardize different types of our pigment carbon black.
