How do a liquid that has just 5 carbon atoms, 2 oxygen atoms and 8 hydrogen atoms be utilized for heavy duty purposes where thermal resistance, electrical resistance and mechanical strength is of prime importance? The solution depends on one word – “Polymerisation”.
Through this infographic, we trace the journey of MMA (Methyl Methacrylate), a liquid monomer which is polymerised to lead to PMMA polymer (Polymethyl Methacrylate), and its various grades.
MMA might be polymerised to PMMA through solution polymerisation, emulsion polymerisation and bulk polymerisation techniques. These reactions happen in a good a catalyst. The resulting polymethyl methacrylate might be modified to varied shapes, sizes and forms with regards to the additives.
The varied grades of SUMIPEX®, the Polymethyl methacrylate resin made 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 make 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 ideal chemical resistance are the properties of the 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 use of this grade in automotive parts including 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 quantities of foreign contaminants can be 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 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 distinction between normal and optical grades/special grades. General Purpose Grades like MH, LG, LG2, etc. also come under “Extrusion Grade”, “Heat Resistance Grade” and “High Flow Grade”. With balanced properties including heat resistance and mechanical strength, this grade is acceptable to create number of products including house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
