SCA’s world-class plant facilities in Singapore position us a manufacturer that has consistently exceeded our customers’ expectations in the last decade. We produce Methyl Methacrylate Monomer (MMA) and Polymethyl Methacrylate (PMMA) at our plants on Jurong Island.



Our MMA Plant and PMMA Plant (SUMIPEX®) are both located on Jurong Island with vertical integration from raw material to product and customers. Raw materials are available through pipelines as well as bulk imports.

SUMIPEX® is the registered trademark of Sumitomo Chemical for its PMMA resins, manufactured in Singapore with a 150,000MT annual production capacity. Sumitomo Chemical Asia is one of the largest PMMA producers in Asia.

Our plants adopt a safe and compact process, which can produce a wide range of product grades from high fluidity resin to low fluidity resin.

Poly Methyl Methacrylate polymer is manufactured by continuous bulk polymerisation of MMA-Monomer. The process is simple, compact, and is highly efficient due to the vertical integration of the MMA and SUMIPEX® PMMA plants. Applications of SUMIPEX® PMMA polymer include general purpose, lens manufacturing, extruded sheets, LCD applications, etc.

Our plants’ utilisation of state-of-the-art manufacturing technologies, together with continual technical support from Sumitomo Chemical, strive to maintain consistent production of high quality products to achieve superior customer satisfaction.

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.
