Technical Information About Acrylic
Acrylic is used in a wide range of industries due to it’s technical properties. It is commonly found in display cabinets, police riot shields, signage, fish tanks and aircraft windows.
Acrylic can be formed and molded using heat. It can be cut with either a laser cutter or circular saw equipped with a special blade. Cut edges can be polished using heat, or buffed using a polishing cloth. It can be joined using special adhesives.
Acrylic, is known as Polymethyl Methacrylate, or PMMA. It is shatter resistant and half the density of glass.
