Mitsubishi Rayon herewith announces that Daesan MMA Corp., a member of the Mitsubishi Rayon Group, commenced commercial production of methyl methacrylate (MMA) monomer and methacrylic acid(MAA) monomer in May. Daesan MMA Corp. is a 50:50 joint venture established in South Korea in August 2006 with Honam Petrochemical Corporation for the purpose of meeting the growing demand for MMA monomer and PMMA (polymethyl methacrylate) resins by the Korean IT sector, whose scale rivals that of China.

Daesan MMA Corp. had already begun operations at a commercial PMMA production plant in September 2008, with an annual production capacity of 40,000 tonnes. The recently commenced production of MMA monomer is taking place at a plant with an annual capacity of 90,000 tonnes, and is being conducted in parallel with production of methacrylic acid (MAA) at an annual capacity of 8,000 tonnes. This gives the company a comprehensive lineup of the principal acrylic products – MMA, MAA, and PMMA.
