How do a liquid which includes just 5 carbon atoms, 2 oxygen atoms and 8 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 your way of MMA (Methyl Methacrylate), a liquid monomer that 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. Every one of these reactions take place in the presence of a catalyst. The resulting sumitomo chemical asia might be modified to various shapes, sizes and forms based on the additives.
Various grades of SUMIPEX®, the Polymethyl methacrylate resin produced 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 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 include 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 including 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 numbers of foreign contaminants bring 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 including 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 including heat resistance and mechanical strength, this grade would work to create wide range of products including house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
