The term "acrylic" is used for products that contain a substance derived from acrylic acid or a related compound. Most often, it is used to describe a clear, glass-like plastic known as poly(methyl) methacrylate (PMMA). PMMA, also called acrylic glass, has properties that make it a better choice for many products that might otherwise be made of glass. There are two basic types: extruded and cast.
Extruded acrylic is made through a process in which the liquid plastic is pushed through rollers, which press it into sheets as it cools. This is a comparatively inexpensive process, but the resulting sheets are softer than cast acrylic, can scratch easier, and may contain impurities. Extruded acrylic is still generally considered to be good quality, and is usually the more common type made available on the market.
Cell cast acrylic tends of be of higher quality than extruded, but it's also more expensive. In cell casting, single sheets are made by pressing the liquid plastic between pieces of a mold, often made of glass, which is then taken through a gradual heating process. The resulting sheet is stronger than extruded acrylic. This type is often used for aquariums, awards, and other products that require shaping or machining of the final product.
Many different products are made from acrylic, including shower doors, bath enclosures, windows, and skylights. It is many times stronger than glass, making it much more impact resistant and therefore safer. Falling against an shower door will not likely break it, for example, and baseballs that crash through glass windows will, in most cases, bounce off acrylic windows. It also insulates better than glass, potentially saving on heating bills.
Acrylic glass is also very clear, allowing 92% of visible light to pass through it. Very thick glass will have a green tint, while acrylic remains clear. It also weathers well, keeping its clarity over the years without turning yellow or breaking down when exposed to sunlight over a long period of time.
Another advantage of acrylic is that it is only half as heavy as glass. This makes this material easier to work with, and makes it a better choice for projects where weight is an issue. It can also be sawed, whereas glass must be scored.
Virtually all major public aquariums now build display tanks out of this thermoplastic, and it is often used in many other buildings. When this material is just over 1 inch thick (about 25 mm), it is bullet resistant; the presidential motorcade, the pope's booth-vehicle, teller enclosures, and drive-through window enclosures all feature bullet-resistant acrylic. It is used for airplane windows as well.
A unique property of this thermoplastic is its ability to be shaped. Extruded acrylic is not as strong as cell cast, and tends to crack or splinter when being machined, so most higher quality products are made from cast acrylic. Structures can also be made with no seams, as chemical welding at the molecular level actually "melts" seams into one piece of solid material. Seams that are welded and polished correctly are invisible.
There are some misconceptions about acrylic, namely that it yellows, turns brittle, and cracks over time. Though this might be true of cheap forms of plastic, it is not so with acrylic. If taken care of, this material can remain new looking for several decades, regardless of age or exposure to sun. Some people worry that it scratches too easily, but unlike glass, scratches may be buffed out.
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. Burning releases toxic fumes, so safety precautions should always be taken when it is being cut with power tools or bent using heat. When it is not cared for properly, or when inferior acrylic is used, it can scratch, and improperly made joints can be very visible.

To the person that asked about bottled water; most bottles are made from PET or PETE. Acrylic is too brittle to use as a simple drink bottle so I don't think anyone can become allergic. Also allergies are not generally due to excessive exposure to a substance, there is more often than not an allergic reaction from the first contact. While we're on the note of bottled water always try and look out for bottles made from PETE as these do not leach chemicals into the water after continuous use and sun light as PET does. |

As a polymer, acrylic is non-organic. That means it takes thousands (no exaggeration) of years to break down.

Acrylic.
Used in the nail bars across the UK to give ladies confidence with natural looking false nails.
A word of warning though, nail bars can be addictive, the odour in the bars can be dangerous if inhaled regularly/constantly and letting a nail technician drill into your nail bed deeply with no complaints could lead to you developing a contagious illness from unsanitary equipment at the worst or at best weaken your natural nails and discourage healthy growth.

Although marble gives you a nicer more appealing look acrylic is better because of the aging properties and its ability to withstand impact whereas marble will crack and chip and is more expensive to replace and repair. expansion is minimal but do use caution when installing, I recommend to my customers to leave a 1/8" gap to allow for expansion. to adhere acrylic to itself you want to use a product called weld-on it is a acrylic type of glue and would work the best. alcohol may stain acrylic but damage would not occur. |
