Just how do a liquid which has just 5 carbon atoms, 2 oxygen atoms and eight hydrogen atoms provide for robust purposes where thermal resistance, electrical resistance and mechanical strength is of prime importance? A better solution depends on one word – “Polymerisation”.
Through this infographic, we trace your journey of MMA (Methyl Methacrylate), a liquid monomer which can be polymerised to cause PMMA polymer (Polymethyl Methacrylate), and it is various grades.
MMA might 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 acrylic glass might be modified to numerous shapes, sizes and forms with respect to the additives.
The assorted grades of SUMIPEX®, the Polymethyl methacrylate resin manufactured 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 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 excellent chemical resistance would be the properties on 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 using 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 mandatory 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. will comw with 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 number of products including house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
