Methyl Methacrylate (MMA) is polymerised to form PMMA (also known as plexiglass), lubricant viscosity modifiers, emulsions, dispersions and coatings.
The weatherability of PMMA can be improved by coextrusion while a copolymer of MMA and an imide monomer increases heat resistance. Methylmethacrylate-butadiene-styrene (MBS) copolymers are used as an impact modifier for clear rigid PVC and in food and pharmaceutical packaging. MMA can partially replace styrene in unsaturated polyester resins to give better weather resistance and longer life.
Methyl methacrylate vapour is irritating to the eyes, nose and throat. Over exposure can lead to headaches, drowsiness and nausea.
ICIS pricing quotes methyl methacrylate in Europe, Asia-Pacific and the USA.
