Carbon Black

Uses: Our company manufactures the black carbon series of superior-wear resisance(N220), high-wear resistance(N330), quick-press(N550), and common(N660) of dry process and wet process, maily applied to various rubber products such as tyres, rubber overshoes, cable, seal ring, tape etc. Moreover they can be applied to such relevant industries as plastic manufacture.
