N220 Carbon Black

Black carbon reinforcement, which gives high wear resistance, high tensile strength and tensile strength of the rubber band. It is widely used for the production of high quality, rubber protection for all types of vehicles, and the protection of the population for renovation. Also used for the production of high quality rubber articles, moldings in difficult conditions. Those. specifications Target PROPERTY Tolerance test method ASTM 1.
