1.Description of carbon black powder:
Chemical Name: Carbon Black
Type:N220/N234/N326/N330/N339/N351/N375/N550/N660/White Carbon Black
Cas no:1333-86-4
Form: black granule or powder
Process: wet or dry process
High-amplifying conductive carbon black powder. Easily dispersed and provides a high level extrudability of rubber compounds. Includes in the tread rubber of tires for passenger cars and trucks. Provides increased wear resistance tires, high resistance to tensile, tolerable tear resistance. Carbon black in tyres is recommended for use in the manufacturing of conveyor belts and other rubber products, which require increased durability.
