Journey from MMA to PMMA – Infographic

How can a liquid which has just 5 carbon atoms, 2 oxygen atoms and eight hydrogen atoms provide for durable purposes where thermal resistance, electrical resistance and mechanical strength is of prime importance? The answer depends on a word – “Polymerisation”.
Through this infographic, we trace right onto your pathway of MMA (Methyl Methacrylate), a liquid monomer which is polymerised to result in PMMA polymer (Polymethyl Methacrylate), and its particular various grades.

MMA might be polymerised to PMMA through solution polymerisation, emulsion polymerisation and bulk polymerisation techniques. All these reactions happen in a good a catalyst. The resulting pmma thermoplastic might be modified to several shapes, sizes and forms based on the additives.
The assorted grades of SUMIPEX®, the Polymethyl methacrylate resin manufactured by Sumitomo Chemical, which are obtained on adding additives are:
• ‘High Impact Grade of SUMIPEX® PMMA’ – Properties like high flow and good heat resistance get this to suited to 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 excellent chemical resistance will be the properties of 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 the usage of this grade in automotive parts like tail lamp, instrument cluster, optical Lens, general lighting fixtures, etc.
• ‘Optical Grades of SUMIPEX® PMMA’ – With excellent heat resistance and flow properties, the optical grades with extremely low levels 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 mandatory 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 difference between 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 works to create wide range of products like house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
