INTRODUTION
Carbon black N220 has high abrasion resistance and crack resistance. Compared to the compounds filled with carbon black N330, those with N220 has higher abrasion of 10%~20%, higher tensile strength and higher crack resistance and it is conductive.
APPLICATION
Carbon black N220 is used in tread compounds of truck tire, passenger tire, high strength rubber productsand high strength conveyor belt.And it is widely used as printing and dyeing materials in plastics color masterbatch, tanneries and paper mill, for its high blackening compared with other products.
