Carbon Black, Silica & Reinforcing Materials

Scientists at the University of South Florida say they have solved a long-standing mystery about why adding tiny particles of carbon black can transform soft rubber into a material strong enough to withstand extreme loads.

The discovery could help manufacturers design stronger, safer and longer-lasting rubber products, including tires, industrial seals and components used in aerospace and energy systems, according to the university.

Orion S.A. announced it is producing circular carbon black at its ISCC PLUS-certified plant in the eastern coastal city of Qingdao, China.

The facility is making three grades — ECORAX® Circular 200, 210 and 215 — from tire pyrolysis oil (TPO). ECORAX® 200 is a hard black suitable for tires, while the 210 and 215 grades can be used for tires and mechanical rubber goods (MRG).

Cabot has long supplied Bridgestone with reinforcing carbon products, and this acquisition further strengthens the partnership between the two companies. In addition, this acquisition expands Cabot’s global manufacturing footprint and reinforces its position as a leading provider of reinforcing carbons. Strategically located near Cabot’s existing facility in Altamira, Mexico, MXCB not only enhances production capacity and operational flexibility but also offers the capability to manufacture a broader range of reinforcing carbon products. This flexibility enables Cabot to better support diverse customer needs and future growth opportunities.

DUNLOP has entered into a Memorandum of Understanding (MOU) with Cabot Corporation to evaluate the commercial adoption of circular reinforcing carbons made with Cabot’s patented regenerated carbon technology. This innovative circular reinforcing carbon powered by Cabot’s EVOLVE Sustainable Solutions incorporates reclaimed carbon derived from the pyrolysis of end-of-life tires and is being considered as a sustainable raw material for Sumitomo Rubber’s tire production.
