Acrylic is an optically transparent thermoplastic material unaffected by moisture and offers a high strength-to-weight ratio. An economical. general-purpose acrylic can be easily heat-formed without loss of optical clarity. Acrylic is used in a wide variety of applications because it can be easily cemented. welded. thermoformed and machined. making it an extremely versatile material suitable for a wide range of applications. Compared to all other types of transparent thermoplastics. acrylic has outstanding resistance to the damaging effects of sunlight and outdoor weathering. Most commercial acrylics have been UV stabilized for good weatherability and resistance to prolonged sunlight exposure. It has FDA approval.
