*N220 Wear and the anti-cracking N110 compared with high, set out low stress, dispersivity is good.

*N330 It with good abrasion resistance and medium hysteresis.

*N550 It in soft carbon black varieties has the best reinforcing performance, excellent extruding

performance, low resilient rate.

*N660 It compared with N550, reinforcing the gender is low, the structure is lower, higher inflation,

mouth filling quantity is bigger.

 

Application

3. Application of carbon black:

Using in rubber industry, painting ,printing ink, NI-MH battery's cathode and other industry.

1.Silicon Rubber: Improves silicon rubbers durability, rebound rate, and anti-distortion performance.

2.Plastics Industry: Improves plastic s tenacity, strength and prevents water absorption.

3.Coating Industry: Prevents agglomeration and drip. Thixotropic  additives.

  Increase denseness and smoothness of paint. 

4.Medicine Industry: Increase denseness ,floating , carrying function in medicine.

  It also can be used as the pesticide powder and anti-agglomeration
