Just how can a liquid which includes just 5 carbon atoms, 2 oxygen atoms and eight hydrogen atoms be used for heavy duty purposes where thermal resistance, electrical resistance and mechanical strength is of prime importance? The result depends on a word – “Polymerisation”.
Through this infographic, we trace your journey of MMA (Methyl Methacrylate), a liquid monomer which can be polymerised to bring about PMMA polymer (Polymethyl Methacrylate), as well as various grades.

MMA might be polymerised to PMMA through solution polymerisation, emulsion polymerisation and bulk polymerisation techniques. Every one of these reactions take place in the use of a catalyst. The resulting pmma suppliers might be modified to several shapes, sizes and forms depending on the additives.
The different grades of SUMIPEX®, the Polymethyl methacrylate resin made by Sumitomo Chemical, which are obtained on adding additives are:
• ‘High Impact Grade of SUMIPEX® PMMA’ – Properties like high flow and good heat resistance choose this well suited for manufacturing extruded sheets/ pipes/ rods, construction materials, automotive parts and industrial applications
• ‘Extrusion Grade of SUMIPEX® PMMA’ – Good extrusion molding characteristics, high surface hardness, superb weatherability and ideal chemical resistance would be the properties of the grade that favour its utilization in extruded sheets/ pipes/ rods.
• ‘Heat Resistant Grades of SUMIPEX® PMMA’ – Excellent heat resistance, excellent surface hardness and mechanical strength enables the usage of this grade in automotive parts like tail lamp, instrument cluster, optical Lens, general lamps, etc.
• ‘Optical Grades of SUMIPEX® PMMA’ – With excellent heat resistance and flow properties, the optical grades with extremely low quantities of foreign contaminants can be used for light Guide panels and optical lenses.
• ‘High Flow Grade of SUMIPEX® PMMA’- With characteristics like high-flow during injection molding and good moldability, this grade is suggested for intricate parts and thin-wall parts molding like watch and clock cover, lighting cover, name plate, house ware, etc.
• ‘General Purpose Grades of SUMIPEX® PMMA’ – General Purpose Grades determine among normal and optical grades/special grades. General Purpose Grades like MH, LG, LG2, etc. are available under “Extrusion Grade”, “Heat Resistance Grade” and “High Flow Grade”. With balanced properties like heat resistance and mechanical strength, this grade is suitable to create wide range of products like house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
