Just how do a liquid that 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 solution lies in one word – “Polymerisation”.
Through this infographic, we trace your way of MMA (Methyl Methacrylate), a liquid monomer that’s polymerised to lead to PMMA polymer (Polymethyl Methacrylate), and it is various grades.
MMA may be polymerised to PMMA through solution polymerisation, emulsion polymerisation and bulk polymerisation techniques. All these reactions happen in a good a catalyst. The resulting sumitomo chemical japan may be modified to several shapes, sizes and forms based on the additives.
The different grades of SUMIPEX®, the Polymethyl methacrylate resin manufactured by Sumitomo Chemical, which can be obtained on adding additives are:
• ‘High Impact Grade of SUMIPEX® PMMA’ – Properties like high flow and good heat resistance get this to 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 the 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 using 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 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 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 distinction between 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 like heat resistance and mechanical strength, this grade is suitable to make great deal of products like house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
