Carbon black is a kind of amorphous carbon. Light, loose and very fine black powder, specific surface area is large, ranging from 10-3000 m2 / g, is organic (natural gas, heavy oil, fuel oil, etc.) under the condition of insufficient air by the incomplete combustion and thermal decomposition products. The proportion of 1.8 2.1.

3.Application
Mainly used in various rubber products such as tyres, rubber overshoes, cable, seal ring, tape etc. Also can be used in relevant industries such as plastic manufacture.Used for rubber intensifier and packing, it is about half of rubber consumption of carbon black with 94% of the total, with approximately 60% for tyre manufacture. In addition, also used for printing ink, paint and plastic colorants and plastic productsscreener of ultraviolet light, as well as important fertilizer.For many other products, such as electrode, dry, resistors, explosives, cosmetics, and polishing compound.
4. Packing
Packed in 25kg/pp bag or customization as client’s request.
5. Storage and Transportation
Store in a cool, dry and ventilated warehouse, avoid heat, fire, oxidant.Due to the carbon black easy to float in the sky, the packing must be in good condition.
