Cabot Corporation
A global specialty chemicals maker headquartered in Boston, Cabot produces carbon black — the fine black powder that strengthens tires and industrial rubber goods — along with fumed metal oxides, battery materials, and inkjet colorants for industries from automotive to electronics. Founded in 1882 by Harvard-trained chemist Godfrey Lowell Cabot, the company was built around a process he patented for turning natural gas by-product into valuable carbon black. Today its EVOLVE® platform also makes sustainable carbons recycled from end-of-life tires, turning old rubber into new raw material.
