Just how do a liquid which includes just 5 carbon atoms, 2 oxygen atoms and 8 hydrogen atoms be used for durable purposes where thermal resistance, electrical resistance and mechanical strength is of prime importance? A better solution is in a word – “Polymerisation”.
Through this infographic, we trace right onto your pathway of MMA (Methyl Methacrylate), a liquid monomer which can be polymerised to bring about PMMA polymer (Polymethyl Methacrylate), as well as various grades.
MMA may be polymerised to PMMA through solution polymerisation, emulsion polymerisation and bulk polymerisation techniques. These reactions happen in the existence of a catalyst. The resulting pmma suppliers may be modified to numerous shapes, sizes and forms with respect to the additives.
Various grades of SUMIPEX®, the Polymethyl methacrylate resin produced 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 get this to 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 the usage of this grade in automotive parts for example tail lamp, instrument cluster, optical Lens, general lamps, etc.
• ‘Optical Grades of SUMIPEX® PMMA’ – With excellent heat resistance and flow properties, the optical grades with extremely low amounts 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 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 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 for example heat resistance and mechanical strength, this grade would work to create great deal of products for example house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
