Journey coming from MMA to PMMA – Infographic

How do a liquid which has just 5 carbon atoms, 2 oxygen atoms and 8 hydrogen atoms supply for high quality purposes where thermal resistance, electrical resistance and mechanical strength is of prime importance? The answer is in a word – “Polymerisation”.
Through this infographic, we trace right onto your pathway of MMA (Methyl Methacrylate), a liquid monomer that’s polymerised to lead to PMMA polymer (Polymethyl Methacrylate), and its particular various grades.

MMA could be polymerised to PMMA through solution polymerisation, emulsion polymerisation and bulk polymerisation techniques. Every one of these reactions happen in a good a catalyst. The resulting pmma polymer could be modified to several shapes, sizes and forms with respect to the additives.
The different grades of SUMIPEX®, the Polymethyl methacrylate resin created by Sumitomo Chemical, which can be obtained on adding additives are:
• ‘High Impact Grade of SUMIPEX® PMMA’ – Properties like high flow and good heat resistance get this to ideal 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 excellent chemical resistance will be the properties of this grade that favour its used in extruded sheets/ pipes/ rods.
• ‘Heat Resistant Grades of SUMIPEX® PMMA’ – Excellent heat resistance, excellent surface hardness and mechanical strength enables use of this grade in automotive parts for example tail lamp, instrument cluster, optical Lens, general light fittings, etc.
• ‘Optical Grades of SUMIPEX® PMMA’ – With excellent heat resistance and flow properties, the optical grades with extremely low numbers 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 difference between normal and optical grades/special grades. General Purpose Grades like MH, LG, LG2, etc. come under “Extrusion Grade”, “Heat Resistance Grade” and “High Flow Grade”. With balanced properties for example heat resistance and mechanical strength, this grade is acceptable to create massive amount products for example house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
