Just how do a liquid that 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 way of MMA (Methyl Methacrylate), a liquid monomer that’s polymerised to cause PMMA polymer (Polymethyl Methacrylate), and it is various grades.
MMA may be polymerised to PMMA through solution polymerisation, emulsion polymerisation and bulk polymerisation techniques. These reactions take place in a good a catalyst. The resulting pmma suppliers may be modified to various shapes, sizes and forms with respect to the additives.
Various grades of SUMIPEX®, the Polymethyl methacrylate resin manufactured by Sumitomo Chemical, which might be obtained on adding additives are:
• ‘High Impact Grade of SUMIPEX® PMMA’ – Properties like high flow and good heat resistance choose 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 ideal chemical resistance are 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 for example 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 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 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 to make wide range of products for example house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
