Today acrylic is used more than ever. Virtually all major public aquariums now build display tanks out of acrylic. You will also find acrylic in malls, institutions, prisons, hospitals and commercial buildings. Acrylic just over one inch thick (32mm) is bullet resistant. The Presidential motorcade, the Pope's booth-vehicle, teller enclosures and drive-through window enclosures all feature bullet-resistant acrylic.
If upgrading the windows in your house, remodeling your bathroom, or adding a beautiful aquarium, consider acrylic. It may cost a little more than glass, but its sheer clarity, light weight and insulating properties make it a superior choice for many applications.There are some misconceptions about acrylic, namely that it yellows, turns brittle and cracks over time. Though this might be true of very cheap forms of plastic[plastic?:Plastic sample cutting machine], it is not so with acry lic. For example, the fighter planes of WWII have acrylic bubble-tops.Airplane windows are also acrylic. If taken care of, acrylic remains new looking regardless of age or exposure to sun.
For all of its advantages, there are two disadvantages of acrylic: it is more expensive than glass, and if exposed to a direct flame it will melt and eventually burn.
