Rubber Additives Carbon Black N326 N774
Product Introduction:
Blackness refers to the intensity of black appearance that carbon black has. When carbon black is used for coloring, the blackness is mainly based on the absorption of light. For a specific concentration of carbon black, the finer the carbon black, the higher the degree of light absorption. In addition to the light absorption inside the carbon black, the blackness is also affected by light scattering with a brightening effect due to the geometric structure of the particle surface, which will reduce the blackness. As the particle size decreases, the degree of light scattering decreases. Only for very fine carbon black, increasing the concentration of carbon black can increase the blackness. For coarse carbon black, the degree of light scattering, which is the dominant factor, increases as the number of carbon black increases, but the blackness decreases accordingly.
Carbon Black are maily used in various rubber products such as tyres, rubber overshoes, cable, seal ring, tape etc. Also can be used in relevant industries such as plastic manufacutre.Different type Carbon Black have different function.Such as N220,Wear and the anti-cracking N110 compared with high, set out low stress, dispersivity is good.N330 is the most common carbon black for tyres.We professional supply Carbon Black N220,N330,N550,N660.We can also supply Pigment grade Carbon Black.If you have any demands for Inorganic pigments such as Iron Oxide pigments,Titanium Dioxide,Carbon Black,Chrome Oxide Green,Chrome Oxide Yellow,C9 Petroleum Resin,Sodium Hexametaphosphate,Sodium Tripolyphosphate, welcome to inquiry us.
