Applications Signs Lamps and lighting soffits Partitions Technical pieces Glazing … Most commercial grades of PMMA, however, are atactic. Clarke, Ed. Camara, R.M. The relatively high surface resistance, however, encourages electrostatic charges on the surface of moulded parts; this can be largely overcome by the use of antistatic agents. Global trade of Poly(methyl methacrylate) is negative in the past few years. To increase its toughness, PMMA is often modified with core-shell rubber or other impact modifers. Cast acrylic sheet and block acrylic have properties that make them suitable for a wide variety of applications.
