BorsodChem MCHZ, s.r.o. is a chemical manufacturing company headquartered in Ostrava, Czech Republic, operating as one of the two production sites of the BorsodChem group in Central Europe.
The company specializes in the production of high-purity organic and inorganic chemical intermediates, with a primary focus on aniline, which constitutes a major share of its output and revenue. Aniline serves as a key raw material for polyurethanes used in automotive, construction, textile, and furniture industries. Other products include cyclohexylamine, dicyclohexylamine, and various amines applied in rubber processing, pharmaceuticals, agriculture, food production, and water treatment.
Established with historical roots dating back to the 1920s as Moravské chemické závody, the modern entity was formed in 2000 following acquisition by BorsodChem. It exports nearly all production, supplying substantial volumes of aniline to its parent company in Hungary while distributing other products across Europe, Asia, and the Americas. The Ostrava facility in Mariánské Hory employs approximately 400 people and has undergone recent investments, including a new nitric acid plant to support downstream processes and improve efficiency and environmental performance.
BorsodChem MCHZ is a wholly owned subsidiary of BorsodChem Zrt. in Hungary, which is part of the Chinese Wanhua Industrial Group. In the global chemical industry, it plays a vital role in the polyurethane supply chain as a reliable producer of essential intermediates.
