Carbon Black

Better Performing, Environmentally Superior Carbon Black

Buy Carbon Black provides high-quality Carbon Blacks and Carbon Black substitutes. Our Carbon Blacks are manufactured with great attention to detail all the way from feedstock procurement to finished manufactured Carbon Black. Our holistic approach provides our customers with better products that feature not only lower prices but those that feature significantly lower emissions profiles than other carbon blacks. Our Carbon Blacks are produced in partnership with world leading industrial Carbon Black partners and are marketed through the our Buy Carbon Black website. Our primary business is the marketing, sales, trading and distribution of quality, more sustainably produced Carbon Blacks and commodities as a whole.

Providing environmentally superior greener carbon blacks.

Buy Carbon Black connects Carbon Black producers with Carbon Black users and buyers directly with producers. Our standard ASTM product lines include the following carbon black grades: N110, N115, N121, N220, N234, N326, N330, N339, N347, N351, N375, N539, N550, N650, N660, N683, N762, N765, N772, N774, ACB2000, ACB5000 with our largest sales volume focused on N500 Series, N600 Series and N700 Series Carbon Blacks.

Today, our ASTM rated Carbon Blacks and alternative CB+ Carbon Blacks are used in – pigmenting (colorants), UV stabilizing and conductive agents in a variety of common and specialty products, including:

Industrial Rubber Products
Plastics
Toners and Printing Inks
Coatings
Electrostatic Discharge (ESD) Compounds

Better Technologies – Yield the Highest Performance Under Extreme Conditions

Hard Carbon Black

Hard carbon black is manufactured by means of the so-called Tread reactor. Extreme temperatures beyond 1900°C, reducing atmosphere, quenching with water and gas velocities beyond the speed of sound require highest quality refractory materials such as high performance mullite or corundum bricks type Korrath and high precision castables.

These Tread reactors also require perfectly shaped bricks to deal with highest gas velocities and pressure differences. Rath choke systems use surface grinded bricks to ensure perfect fit and as a result longest life. Rath carbon black chokes are made from Korrath corundum and chromium corundum bricks.

Soft Carbon Black

The Carcass reactor is used to produce soft carbon black. Horizontal and vertical designs are in service, which each create new refractory challenges. These reactors operate at slightly lower temperatures than Tread reactors.

However Carcass reactors pose a challenge due to size and the use of alkali additives. Temperatures usually don’t exceed 1600°C and permit the use of mullite bonded corundum bricks.
