Fit for purpose carbon blacks from regional sources provide the required performance with short supply chains and world class technical support available globally.
Birla Carbon offers carbon blacks that meet the color requirements of the newsink/coldest market. There is a balance between the desire for low viscosity inks, and ease of dispersion, which is primarily adjusted through the use of different levels of structure.
- Higher structure carbon blacks will favor dispersibility and give a higher viscosity
- Lower structure carbon blacks provide the lower viscosity, though these will be slightly harder to disperse
- The typical ink will be produced using locally sourced beaded carbon blacks, though some local markets still prefer powder carbon blacks even for newsinks.
Areas of Benefits:
BALANCE OF COLOR PROPERTIES
The typical newsink formulation may use two different carbon blacks, a higher surface area for jetness, and a second lower surface area pigment to bring out a bluer tone. Blending is usually done at the ink base stage, rather than co-grinding the pigments.
RHEOLOGY
With modern press speeds, the demand on ink rheology is higher than at any time previously. A move to lower structure materials helps meet these rheological needs.
REGIONAL AVAILABILITY
By bringing the product to you from a local production source, we provide reliable and short supply chains.
OUR PRODUCTS
| Product Name | Description | Data Sheet | SDS | Contact |
|---|---|---|---|---|
| Raven L Ultra | Raven L Ultra is a medium-low structure carbon black with moderate surface area which balances color performance with flow properties and dispersibility. The high level of purity generates low abrasion inks. The product is especially suited for gravure applications. |  |  |  |
| N330 & N660 | This high structure pairing is a standard in the industry, offering good dispersion rates with a balance of bluetone. | | | |
| N326 & N772 | This pairing with a lower structure level , gives similar color and low viscosity, though there will be increased dispersion time. | | | |
| Raven 900 P | Raven 900 is a moderate structure, powder carbon black design to enable rapid, more thorough dispersion and limit pigment penetration into porous substrates. The product is especially suited for flexographic inks. | | | |
| Raven M | A workhorse product for the newsink industry, providing good color strength and ease of dispersion with a medium-high structure. | | | |
| Raven 415 | A lower surface area carbon black, which can be blended with the higher strength products to provide the desired blue tone. | | | |
| Raven 1010P | A powder product with greater jetness than Raven 900 for the regional markets that require this physical form | | | |
| Raven 880 | TBD | | | |
| Raven 425 | A bluer tone powder product, than can be blended with other powder products to reach the desired color space. | | | |
