Acrylic plastic, which is a polymer of methyl methacrylate also known as polymethyl methacrylate, is engineered to be stronger than glass while still appearing glass-like. It is used to make drink and food containers that will not break when dropped a short distance. It's strength is limited, however, because it cannot withstand bullets or explosion impacts.
Acrylic plastic is also resistant to weather damage. It is waterproof and does a superb job of keeping out rain when properly sealed, like window glass. However, unlike regular window glass, it can resist strong winds and certain debris, such as small tree limbs, tossed during hurricanes and tornadoes.
Acrylic plastic is also renown for its optical clarity. It can be manufactured to be as transparent as glass. Because of this quality, acrylic plastic is used to make high-strength eyeglasses and lenses used in microscopes and other instruments.
Some types of acrylic plastic are also heat resistant. They can withstand high temperatures without melting or deforming and without releasing harmful smoke. These types of acrylic plastic are used in high-heat lamps and light fixtures.
There are a few other desirable properties of acrylic plastic. It is relatively cheap to produce in large quantities, which is why it is widely available. Most types of acrylic plastic are also not sensitive to ultraviolet radiation. It can be easily molded, shaped and cut. Additionally, it is a good insulator for electrical components and is resistant to bacteria and some chemicals. Lastly, it can withstand extreme pressure and has been used in deep sea vessels.
