Nippon Aluminum Alkyls produces co-catalysts for polyolefins
Mitsui Chemicals and Ketjen Netherlands Holdings B.V. have entered into a share purchase agreement for Nippon Aluminum Alkyls, a company engaged in the manufacturing and sales of organometallic compounds such as alkyl aluminum.
As of today, Mitsui Chemicals has acquired all shares of NAA, which are held by Ketjen, making it a wholly owned subsidiary.
Since its establishment in 1968, NAA has been manufacturing and selling a wide range of high-quality alkyl aluminum products. Their applications span a wide range of uses that support industry and society, including catalysts for polyolefins, reducing agents for pharmaceutical synthesis, raw materials for asymmetric synthesis catalysts, and raw materials for electronic information materials.
Ketjen is a provider of advanced catalysts solutions to leading producers in the petrochemical, refining, and specialty chemical industries. “We are excited that NAA will be acquired by a company like Mitsui that is dedicated to fostering the growth of this business,” said Ketjen President Michael J. Simmons.
