It usually consists of an acrylic monomer of methyl methacrylate (typically supplied as a powder) that becomes a polymer (polymethylmethacrylate or PMMA) when mixed with a catalyst such as benzoylperoxide (typically supplied as a liquid). Reinforcing fillers may be included in the resin to increase its strength and/or durability.
