Nano-scale conductive carbon black means that the particle size of carbon black is nano-scale. It is generally believed that the particle size is generally considered to be below 100nm and can be called nano-scale.
Nano-scale conductive carbon black technical indicators:
Iodine absorption value (g/kg) 700-900
DBP absorption value (10-5m3/kg) 400-500
Nitrogen adsorption specific surface area (103m2/kg) 800-900
Heating loss (%) maxl
Powder resistivity (Ω.cm) 0.12
Average particle size (nm) 30-40
Ash (%) ≤5-8
What are the uses of nano-scale conductive carbon black?
Nano-scale conductive carbon can be used in plastics, rubber, coatings, and inks. It can be said that carbon black for plastics, carbon black for conductive rubber, carbon black for conductive coatings, and carbon black for conductive inks can all use nano-scale conductive carbon.
Suggestions for the addition of nano-scale conductive carbon black:
In plastics and rubber, the resistance can reach 106 if it is added to 6-7%;
Generally, only 5-6% resistance needs to be added to paint and oil to reach 105;
In PVC products, it is necessary to increase the dosage appropriately.
