How do a liquid that has just 5 carbon atoms, 2 oxygen atoms and 8 hydrogen atoms be utilized for durable purposes where thermal resistance, electrical resistance and mechanical strength is of prime importance? The result lies in a word – “Polymerisation”.
Through this infographic, we trace the journey of MMA (Methyl Methacrylate), a liquid monomer which can be polymerised to lead to PMMA polymer (Polymethyl Methacrylate), and its various grades.
MMA may be polymerised to PMMA through solution polymerisation, emulsion polymerisation and bulk polymerisation techniques. All these reactions occur in a good a catalyst. The resulting pmma suppliers may be modified to several shapes, sizes and forms with regards to the additives.
Various grades of SUMIPEX®, the Polymethyl methacrylate resin manufactured by Sumitomo Chemical, that are obtained on adding additives are:
• ‘High Impact Grade of SUMIPEX® PMMA’ – Properties like high flow and good heat resistance choose this 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 excellent chemical resistance will be the properties of this grade that favour its use within 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 like tail lamp, instrument cluster, optical Lens, general lights, 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 mandatory for intricate parts and thin-wall parts molding like 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. will comw with under “Extrusion Grade”, “Heat Resistance Grade” and “High Flow Grade”. With balanced properties like heat resistance and mechanical strength, this grade works to create great deal of products like house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
