Main Product: MMA monomer


Methyl Methacrylate Monomer is manufactured by oxidation of isobutylene. The process does not use any toxic raw material and does not produce waste acid by-products. Applications include cast sheets, plastic modifiers, emulsions for paints/adhesives, etc. MMA is also used as a raw material for SUMIPEX® PMMA Polymer.

Our plants are constructed based on Sumitomo Chemical’s innovative technology and state-of-the-art manufacturing processes. In addition, it is a safe and reliable process that does not utilize any highly toxic raw materials. It is also capable of producing monomers that are suitable for optical grade polymers.
