Carbon black is a common material used in the production of various industrial products, such as tires, rubber goods, and coatings. Among the various types of carbon black, N330 and N660 are two popular choices. In this article, we will discuss the differences between these two types of carbon black.
1.Particle size
One of the main differences between N330 and N660 is their particle size. N330 has a smaller particle size, typically ranging from 20 to 50 nm, while N660 has a larger particle size, typically ranging from 30 to 70 nm. This difference in particle size can affect the properties of the end product.
2.Surface area
Another difference between N330 and N660 is their surface area. N330 has a lower surface area, typically around 75 m2/g, while N660 has a higher surface area, typically around 35 m2/g. This difference in surface area can affect the ability of the carbon black to absorb and adsorb various substances.
3.Tinting strength
Tinting strength is a measure of the ability of carbon black to produce a dark, intense color when added to a material. N330 has a higher tinting strength than N660, which means that it can produce a darker color when added to a material.
4.Cost
The cost of N330 and N660 can also differ. N660 is generally more expensive than N330, due to its larger particle size and higher surface area.
In conclusion, while both N330 and N660 are types of carbon black, they differ in particle size, surface area, tinting strength, and cost. Understanding these differences can help manufacturers choose the most suitable carbon black for their products.
