For officials of Shoreline, WA, USA, the artwork for its new City Hall had to capture the essence of the young city as well as be environmentally friendly enough to help the building achieve LEED certifications. The combination of a local artist’s vision and a unique acrylic made those lofty goals attainable. More

Acrylic Lights Up Restaurant in South Korea
When the man who refers to himself as “The Famous Michael Chow” decided to create his Mr. Chow Seoul, he was already familiar with the development, fabrication and application of acrylic.

Working closely with engineers, his design was brought to reality by the flexibility and durability of acrylic. More

Technical Advisory
• When selling acrylics, remember that transparency, gloss and dimensional shape of acrylics are virtually unaffected by years of exposure to the elements, salt spray or corrosive atmospheres.

Acrylics withstand exposure to light from fluorescent lamps without darkening or deteriorating. They ultimately discolor, however, when exposed to high-intensity UV light below 265 nm. Special formulations resist UV emissions from light sources such as mercury-vapor and sodium-vapor lamps.

• Mechanical properties of acrylics are high for relatively short-term loading. High stresses can be sustained safely for short periods, but for long-term service, tensile stresses must be limited to 1,500 psi (10 MPa) to avoid crazing or surface cracking.

• Acrylic plastics are among the most scratch resistant of all thermoplastics. Toughness of acrylic sheet, as measured by resistance to crack propagation, can be improved by inducing molecular orientation during forming. Jet aircraft cabin windows, for example, are made from oriented acrylic sheet.

Sustainability of Plastic: Did You Know…
• Without plastics, the total volume of packaging waste would increase by around 160 percent.

• Because plastics are lightweight, durable and versatile, manufacturers can minimize the material used and the waste generated by using plastic products and packaging.

• During their life cycle, plastic bags require about one-third less energy to make than paper bags.

• It takes 4.3 lbs. of glass to package one gallon of milk or juice, but less than 1/4 lb. of plastic to do the same job.
