Outstanding resistance to long-term exposure to sunlight and weathering. Low water absorption. Thermoformable. Good electrical resistivity. Excellent optical properties. Acrylic finished plastics have outstanding resistance to long-term exposure to sunlight and weathering. It has excellent optical properties and is more resistant to impact than glass. In addition, acrylic has low water absorption, good electrical resistivity, and fair tensile strength.Applications are infinite, including art installations, outdoor signs, glazing, aircraft canopies, skylights, auto tail-lights, dials, buttons, lighting applications, knobs, and machine covers. Interstate Plastics offers a wide variety of Acrylic plastics to fit your specific application. Acrylic is often preferred because of its moderate properties, easy handling and processing, and low cost, but behaves in a brittle manner when loaded, especially under an impact force. Transmits up to 92% of visible light (3 mm thickness), and gives a reflection of about 4% from each of its surfaces on account of its refractive index. It has a density of 1.17-1.20 g/cm3, which is less than half that of glass. It also has good impact strength, higher than both glass and polystyrene.
