*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.
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
4. Packing and storage of Carbon Black
1,The soft packages, which were made of PP material, commonly we provide 500Kg per pack, 800Kg per pack, and 1000Kg per pack.
2,The packages of 25Kg, which were made of PP material or Kraft papers, could be transported in bulk, we also could transport a bracket which contained 1000Kg with protective films covered, which we called tons coating transport.
3, Special specifications on the package are acceptable.
Keep the product un-stacked in dry and closed rooms at normal temperature and air humidity. To achieve best possible results, we recommend storage under the condition stated above and use within 12 months from delivery. Avoid breathing duct when handling, and wash with soap & water in case of skin contact.
