How do a liquid which has just 5 carbon atoms, 2 oxygen atoms and eight hydrogen atoms be used for high quality purposes where thermal resistance, electrical resistance and mechanical strength is of prime importance? The answer is in a word – “Polymerisation”.
Through this infographic, we trace your journey of MMA (Methyl Methacrylate), a liquid monomer that’s polymerised to result in PMMA polymer (Polymethyl Methacrylate), and its various grades.
MMA may be polymerised to PMMA through solution polymerisation, emulsion polymerisation and bulk polymerisation techniques. These reactions occur in the use of a catalyst. The resulting sumitomo chemical japan may be modified to varied shapes, sizes and forms with respect to the additives.
The assorted grades of SUMIPEX®, the Polymethyl methacrylate resin made by Sumitomo Chemical, that are obtained on adding additives are:
• ‘High Impact Grade of SUMIPEX® PMMA’ – Properties like high flow and good heat resistance get this to 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 would be the properties of this 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 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 usually recommended 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 among normal and optical grades/special grades. General Purpose Grades like MH, LG, LG2, etc. are available under “Extrusion Grade”, “Heat Resistance Grade” and “High Flow Grade”. With balanced properties for example heat resistance and mechanical strength, this grade is suitable in making massive amount products for example house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
