Carbon Black N220 is recommended to be used in the tread rubber of tires for heavy lorries, for ordinary cars, and the rubber products required for high strength and high wear resistance.
N220 are fits for all kinds of rubbers, while wear resistance intensity is 10%-20% higher than N330. Furthermore, N220 could provide high stretching intensity, high resisting avulsion intensity, and high electric conductivity, but it is easily getting heated and very hardness.
