A3 Orange Acrylic sheet comes with paper masking on both sides, which is generally brown or white. This protects your acrylic sheet from minor scratches. All you need to do is just peel off. Acrylic cast acrylic sheet offers superb optical clarity and optimum performance. Acrylic is durable enough for cutting, drilling, routing, cementing, polishing or thermoforming. LIGHT IN WEIGHT (specific gravity 1.19) is less than half the weight when compared to inorganic glass. CHEMICAL RESISTANT is resistant to inorganic chemicals and normal chained hydrocarbons. However, contact with organic solvents may cause swelling, crazing, or cracking. IMPACT RESISTANT is approximately 8 to 10 times more resistant to impact than ordinary plate glass. EASY FABRICATION can be saw cut, drilled, routed, machined, solvent cemented, polished and strip bent using conventional acrylic sheet fabrication techniques. THERMO FORMABLE An excellent thermoplastic, it may be thermoformed. Because Acrylic cast is a cell cast sheet, it is not subject to the excessive shrinkage that is encountered in extruded or continuously manufactured sheets.
