Acrylic general description acrylics polymethyl methacrylate or pmma is an amorphous thermoplastic which is optically. Thermal expansion can present significant challenges for designers in certain areas for example when constructing spacecraft aircraft buildings or bridges but it can have positive uses. Plexiglas acrylic sheet will expand and contract with changes in temperature and humidity. Range perspex cell cast acrylic sheet is available in clear opal and many colours in a range of thicknesses sizes and special grades.
