At Buy Carbon Black, we specialize in providing high-quality carbon blacks and eco-friendly alternatives. Our products, including ASTM-rated grades like N110, N220, and N330, are perfect for industries such as rubber, plastics, and coatings.
Buy Carbon Black provides high-quality Carbon Blacks and Carbon Black substitutes. Our Carbon Blacks are manufactured with great attention to detail, from feedstock procurement to finished manufacturing. Our holistic approach provides our customers with better products with lower prices and significantly lower emissions profiles than carbon blacks. Our Carbon Blacks are produced in partnership with world-leading industrial Carbon Black partners and are marketed through our Buy Carbon Black website. Our primary business is the marketing, sales, trading, and distribution of quality, more sustainably produced Carbon Blacks and commodities.
Providing environmentally superior greener carbon blacks.
Buy Carbon Black connects Carbon Black producers with 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 most significant sales volume focused on N500 Series, N600 Series, and N700 Series Carbon Blacks.
Today, our ASTM rated Carbon Blacks, and alternative Sustainable Carbon Blacks (sCB) are used in – pigmenting (colorants), UV stabilizing, and conductive agents in a variety of standard and specialty products, including:
Sustainable CB Carbon Black Fillers, Alternatives & Substitutes
We are proud to be a leading global supplier of specialized, environmentally friendly Carbon Blacks used as reinforcing fillers and versatile, commercially accepted substitutes for industrial-grade Carbon Black applications. Our group now distributes and produces over 100,000 metric tons of blended sCB Carbon Blacks annually. We also work with high-quality producers of tire pyrolysis-derived char to produce recovered carbon black (rCB) blends, for which we have significant customer demand.

Better Technologies – Yield the Highest Performance Under Extreme Conditions
Hard Carbon Black
Hard carbon black is manufactured utilizing the so-called Tread reactor. Extreme temperatures beyond 1900°C, reducing atmosphere, quenching with water, and gas velocities beyond the speed of sound require the 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 the highest gas velocities and pressure differences. Rath choke systems use surface-ground bricks to ensure perfect fit and, as a result, the 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, creating new refractory challenges. These reactors operate at slightly lower temperatures than Tread reactors.
However, Carcass reactors pose a challenge due to their size and the use of alkali additives. Temperatures usually don’t exceed 1600°C, which permits the use of mullite-bonded
corundum bricks.
