Journey via MMA to PMMA – Infographic

Just how do a liquid which includes just 5 carbon atoms, 2 oxygen atoms and 8 hydrogen atoms be utilized for robust 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 lead to PMMA polymer (Polymethyl Methacrylate), and it is various grades.

MMA could 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 could be modified to several shapes, sizes and forms based on the additives.
The different grades of SUMIPEX®, the Polymethyl methacrylate resin created by Sumitomo Chemical, which might be obtained on adding additives are:
• ‘High Impact Grade of SUMIPEX® PMMA’ – Properties like high flow and good heat resistance get this suitable 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 will be the properties of the 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 the application of this grade in automotive parts like tail lamp, instrument cluster, optical Lens, general lights, etc.
• ‘Optical Grades of SUMIPEX® PMMA’ – With excellent heat resistance and flow properties, the optical grades with extremely low quantities of foreign contaminants are 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. will comw with under “Extrusion Grade”, “Heat Resistance Grade” and “High Flow Grade”. With balanced properties like heat resistance and mechanical strength, this grade would work to create number of products like house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
