W.R. Grace & Co.

W. R. Grace and Co. is an American chemical business based in Columbia, Maryland. It produces specialty chemicals and specialty materials in two divisions: Grace Catalysts Technologies, which makes polyethylene and polypropylene catalysts and related products and technologies used in petrochemical, refining, and other chemical manufacturing applications, and Grace Materials and Chemicals, which makes specialty materials, including silica-based and silica-alumina-based materials, which are used in commercial products such as sunscreen and in chemical process applications. For much of its early history, Grace's main business was in South America, in maritime shipping, railroads, agriculture, and silver mining, with 30,000 employees in Peru. In the 1950s, Grace began to diversify and grew into a Fortune 100 worldwide conglomerate. After emerging from a prolonged bankruptcy period of 12 years in 2014, the company spun off its other major operating divisions. In 2015, Grace separated into two independent public companies. Its Catalysts and Material Technologies business segments remained in Grace, and what would later become GCP Applied Technologies Inc. held its Construction Products and Darex Packaging Technologies businesses. In September 2021, Standard Industries acquired Grace (the Catalysts and Material Technologies business segments). In December of 2021, GCP Applied Technologies was acquired by Saint-Gobain, a global leader in construction chemicals.
