1. TFCC carbon black series are collected from incompletely burned carbonaceous materials. They are protogenesis particles and become high dispersing carbon black pigments after special treatment. We used the technique which is able to produce the smallest particle diameter powder which would be packed right after they are collected from oil burning. That creates finely dispersed black pigment.

2. Carbon black pigment atom does not exist single. Each one forms micrograined structure with others and different structure form again with each other. See the following diagram.：

Many carbon black factories granulate the carbon black powder into bigger particles so as to pack and transport easily. However the bigger particles have worse dispersivity.

TFCC carbon black series are collected from incompletely burned carbonaceous materials. They are protogenesis particles and become high dispersing carbon black pigments after special treatment. TFCC carbon black has extreme high blackness and some items can replace the similar products of the famous brands in the world.

TFCC carbon black series are widely applied in engineering plastics, and PVC,TPR granulation process and color master batch, lacquer, printing ink, stoving varnish coating process.

　　 　

3. Physical Parameter of Carbon black pigment.

a. Particle diameter means the diameter of a single(random) particle generated in the burning of a sort of oil. Average particle diameter means extracting some particles of limited weight or unit weight and calculating the average particle diameter.

b. specific surface area means the area that a unit weight powder occupys. This figure is related to particle diameter.

c. DBP absorption value, means the oil absorption volume of unit weight. In general, the less absorption value, the better glossiness in pigment product.

d. PH, the best is neutral, that is PH≈7. That would be good to the plastic performance.

e. Blackness, some factories measure the blackness with iodine absorption number. The higher iodine absorption number , the higher blackness.

Special notice:

A.The oil absorption value is inversely proportional to the glossiness of products. The less oil absorption value of raw materials, the higher glossiness of products.

B.Blackness is inversely proportional to dispersivity. The higher blackness, the worse dispersivity.　

C.TFCC carbon black is specially treated. It keeps a finely dispersed performance with higher blackness.
