Just how can a liquid which includes just 5 carbon atoms, 2 oxygen atoms and eight hydrogen atoms provide for high quality purposes where thermal resistance, electrical resistance and mechanical strength is of prime importance? The result depends on a word – “Polymerisation”.
Through this infographic, we trace your way of MMA (Methyl Methacrylate), a liquid monomer which is 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. All these reactions take place in a good a catalyst. The resulting pmma suppliers may be modified to numerous shapes, sizes and forms based on the additives.
The varied grades of SUMIPEX®, the Polymethyl methacrylate resin produced 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 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 excellent chemical resistance are the properties of this grade that favour its used 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 like 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 quantities 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 recommended 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 contrast 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 like heat resistance and mechanical strength, this grade is suitable to make wide range of products like house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
