The company focused on specialty chemicals for various industrial sectors, and these were transportation (including automotive), energy, agriculture, and electronics. Chemtura operated manufacturing plants in 11 countries, including Canada.

Chemtura Corporation was the successor to Crompton & Knowles Corporation, which was incorporated in Massachusetts in 1900 and engaged in the manufacture and sale of specialty chemicals beginning in 1954. Crompton & Knowles traces its roots to Crompton Loom Works incorporated in the 1840s. In 2005, Crompton acquired Great Lakes Chemical Company, Inc., of West Lafayette, Indiana, to form Chemtura Corporation. Additionally, Great Lakes Chemical Corporation still existed as a subsidiary company of Chemtura. On April 21, 2017, Chemtura was officially acquired by Lanxess for $2.1 billion in cash.

In Canada, Chemtura and its predecessor corporations operated a plant in Elmira, Ontario. Since 1941 the plant has undergone various name and ownership changes. From 1966-2000 the plant operated as Uniroyal Chemical, from 2000-2006 as Crompton Company, and on July 1, 2006 formally changed its name to Chemtura Canada Company.
