Acrylic vs. Glass Danielle McBroom Matt Ziff Self-Selected Presentation
Acrylic Glass • Most commonly know as Plexiglas. • Developed in 1928 and appeared on the market in 1933 by Rohm and Haas Company. • It is a transparent plastic and thermoplastic. • Thermoplastic- polymer that turns to liquid when heated and freezes when cooled sufficiently. • There are two common types of acrylic glass, cell and extruded. • It has moderate properties, is easy to handle and process, and has a low cost. • The melting point of acrylic glass is 265-285 F which gives it a level 3 fire rating. • Acrylic glass used as windows helps to insulate homes better. • Acrylic Glass is the most clear material with a 93% transparency rating.
Uses of Acrylic Glass • Lenses of exterior lights of automobiles • Hockey Rinks • Viewing ports in submersibles • Can replace eye lenses removed due to Cataracts • Bone cement • Dentures • CD’S and DVD’S • Artificial Fingernails • Electric Guitars • Drum Sets • Casing for Apple Computers • High heel shoes • LED Signs • Jewelry
Acrylic Glass and Sustainability • Acrylic glass is recyclable. • It is categorized under plastic group 7. • If processed correctly, Acrylic Glass will not release harmful pollutants into the air. • It can be incinerated for thermal recycling or physical/chemical recycling.
Acrylic Glass and Sustainability • Recently, a way to make purely organic Acrylic Glass has been discovered. • This new technique involves straining bacteria to find enzymes that could be used in biotechnological production. • The enzyme is called 2- hydroxyisobutyryl. • In the future, it will be made of alcohol, sugars, or fatty acids. • The new product, “O-Glas” or “Piacryl”, is made with an enzyme that will change raw materials into the components needed to make the glass.
Glass • Inorganic product • It has been around since 12,000B.C.E. • Includes silica, calcium oxide, magnesium oxide, and aluminum oxide. • Glass soes not fall under the categories of liquid, solid, or gas. It is classified as a rigid liquid or amorphous solid. • Glass is favored because it resist chemical reactions, does not release chemicals, and can withstand heat and cold. • Color can be added to glass. Also, other substances can be used to “frost” or fog glass.
Uses of Glass • Windows • Display cases • Eye Glasses • Architectural purposes • Eating utensils such as drinking glasses, dishes, and bowls. • Car windshields
Acrylic Glass vs. Glass • Acrylic glass is easily scratched, whereas glass is hard to scratch. However, the scratches can be buffed out. • Glass can weigh 4 to 10 times more than glass. • Glass is highly breakable. Acrylic glass can withstand high impact. • Acrylic glass can be shaped virtually any way desired. It can be melted at corners so that there are no seams.Glass is difficult to bend and looses strength when bent.
