Acrylics properties
Acrylic plastics are known for their attractive, glossy surfaces, in practically any color. The problem is that in large, three-dimensional parts, acrylic moldings are not rigid enough for some requirements. One answer to the problem is provided by a process called "rigidizing." Rigidizing marries a thin thermoformed acrylic shell to a strong underlayer of glass-reinforced polyester. Adhesion is excellent and the results are being seen in successful applications such as tops for vans and other RVS.

The light weight and toughness of clear plastic sheet qualifies it for many jobs formerly held by glass. Materials in this category include acrylics, cellulosics, polyarylates, polysulfones and polycarbonates. Despite the durability of these materials, however, their surfaces are softer than those of glass, making them more suseptible to hazing by surface abrasion and to damage by scratching. But progress is being made, and more abrasion-resistant materials and surface treatments are being developed.
