How do a liquid which includes just 5 carbon atoms, 2 oxygen atoms and 8 hydrogen atoms supply 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 the journey of MMA (Methyl Methacrylate), a liquid monomer that’s polymerised to bring about PMMA polymer (Polymethyl Methacrylate), and it is various grades.
MMA might be polymerised to PMMA through solution polymerisation, emulsion polymerisation and bulk polymerisation techniques. Each one of these reactions occur in a good a catalyst. The resulting sumitomo chemical asia might be modified to several shapes, sizes and forms with respect to the additives.
The assorted grades of SUMIPEX®, the Polymethyl methacrylate resin created 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 to suited to 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 include the properties with this 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 using this grade in automotive parts for example tail lamp, instrument cluster, optical Lens, general lighting fixtures, 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 for example 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. come under “Extrusion Grade”, “Heat Resistance Grade” and “High Flow Grade”. With balanced properties for example heat resistance and mechanical strength, this grade is suitable to create number of products for example house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
