Journey coming from MMA to PMMA – Infographic

How do a liquid that has just 5 carbon atoms, 2 oxygen atoms and eight hydrogen atoms provide for high quality purposes where thermal resistance, electrical resistance and mechanical strength is of prime importance? The solution lies in one word – “Polymerisation”.
Through this infographic, we trace the journey of MMA (Methyl Methacrylate), a liquid monomer that is polymerised to bring about PMMA polymer (Polymethyl Methacrylate), as well as various grades.

MMA may be polymerised to PMMA through solution polymerisation, emulsion polymerisation and bulk polymerisation techniques. These reactions occur in the use of a catalyst. The resulting polymethyl methacrylate may be modified to several shapes, sizes and forms based on the additives.
The assorted grades of SUMIPEX®, the Polymethyl methacrylate resin created by Sumitomo Chemical, that are obtained on adding additives are:
• ‘High Impact Grade of SUMIPEX® PMMA’ – Properties like high flow and good heat resistance make 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 with this grade that favour its use in extruded sheets/ pipes/ rods.
• ‘Heat Resistant Grades of SUMIPEX® PMMA’ – Excellent heat resistance, excellent surface hardness and mechanical strength enables using this grade in automotive parts for example 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 amounts of foreign contaminants can be used 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 for example 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. will comw with under “Extrusion Grade”, “Heat Resistance Grade” and “High Flow Grade”. With balanced properties for example heat resistance and mechanical strength, this grade would work to create great deal of products for example house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
