ACRYLIC EXTRUDED
Acrylic is a clear thermoplastic with approximately 92% transparency, making it useful in many optical applications. It is also a good electrical insulator for low frequencies and has resistance to weathering. Acrylic can be heat formed/thermoformed, as well as solvent cemented. Extruded acrylic typically has a lower molecular weight compared to cast acrylic and continuously manufactured acrylic. Well-known trade names are Plexiglas, Optix, Lucite, Chemcast and Polycast.
