How do a liquid which 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? The answer is based on a word – “Polymerisation”.
Through this infographic, we trace right onto your pathway of MMA (Methyl Methacrylate), a liquid monomer that is polymerised to lead to PMMA polymer (Polymethyl Methacrylate), as well as various grades.
MMA might be polymerised to PMMA through solution polymerisation, emulsion polymerisation and bulk polymerisation techniques. These reactions occur in the use of a catalyst. The resulting pmma suppliers might be modified to varied shapes, sizes and forms with respect to the additives.
Various grades of SUMIPEX®, the Polymethyl methacrylate resin created by Sumitomo Chemical, that are obtained on adding additives are:
• ‘High Impact Grade of SUMIPEX® PMMA’ – Properties like high flow and good heat resistance get 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 ideal chemical resistance include the properties of this 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 using this grade in automotive parts including 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 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 usually recommended for intricate parts and thin-wall parts molding including 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. are available under “Extrusion Grade”, “Heat Resistance Grade” and “High Flow Grade”. With balanced properties including heat resistance and mechanical strength, this grade would work to create wide range of products including house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
