1.Carbon Black 
2.N330,N220,N550,N660, N774 
3.ISO.with competitive price 
4.Used as rubber reinforcing agent

N220 Can give a good rubber tensile properties, tear resistance, abrasion resistance , dispersivity is good.

♦ N330 has good abrasion resistance and medium hysteresis.

♦ N550, It is soft carbon black varieties has the best reinforcing performance, excellent extruding performance, low resilient rate.

♦ N660, compared with N550, its reinforcing is lower, but the structure is lower, higher inflation,mouth filling quantity is bigger.
