How do a liquid containing just 5 carbon atoms, 2 oxygen atoms and eight hydrogen atoms provide for durable purposes where thermal resistance, electrical resistance and mechanical strength is of prime importance? A better solution lies in one word – “Polymerisation”.
Through this infographic, we trace right onto your pathway of MMA (Methyl Methacrylate), a liquid monomer that’s polymerised to bring about PMMA polymer (Polymethyl Methacrylate), and its particular various grades.

MMA might be polymerised to PMMA through solution polymerisation, emulsion polymerisation and bulk polymerisation techniques. Every one of these reactions happen in a good a catalyst. The resulting pmma suppliers might be modified to several shapes, sizes and forms based on the additives.
The varied 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 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 with 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 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 numbers of foreign contaminants are 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 difference between normal and optical grades/special grades. General Purpose Grades like MH, LG, LG2, etc. also come under “Extrusion Grade”, “Heat Resistance Grade” and “High Flow Grade”. With balanced properties like heat resistance and mechanical strength, this grade works to create number of products like house ware, stationery, telephone buttons, piano keys, electrical accessories, ornaments, etc.
