Sumitomo Chemical Asia Pte Ltd (SCA), a subsidiary of Sumitomo Chemical, was established with the primary aim of manufacturing and selling MMA monomer and SUMIPEX® PMMA polymer.

MMA Monomer

mmaMethyl methacrylate (MMA) is an organic compound and a colourless liquid. Primarily used in the manufacturing process of poly methyl methacrylate acrylic plastics (SUMIPEX® PMMA polymer), MMA is also used to produce the co-polymer – methyl methacrylate-butadiene-styrene (MBS), used as a modifier for poly vinyl chloride (PVC). Apart from its use in the manufacturing industry, an alternative application of MMA is as cement used for total hip and knee replacements.


pmmaAlso known as Acrylic Glass, SUMIPEX® PMMA Polymer is manufactured from MMA Monomer. It is a transparent thermoplastic, used in sheet form as a lightweight, shatter-resistant alternative to glass, thus deriving its name Acrylic Glass. SUMIPEX® PMMA polymer is also used as a casting resin, in inks and coatings, and in several other applications.
