PET for Laboratories:
PET is a good choice for labware because of its many desirable characteristics. PET is available in a wide range of colors, shapes, and sizes. Darker colored PET plastic containers are best for blocking UV rays from light sensitive materials. PET is highly resistant to diluted acids, oils, and alcohols.
Recycling:
PET can be identified easily by locating its recycling code symbol. PET is denoted by the familiar triangular shaped arrows with the number 1 in the center. PET can be recycled into many other products besides bottles and jars. Other recycled PET products include ski coat fibers, fleece vests, and sleeping bag lining. For more information regarding PET recycling see the Plastic Container Recycling Page.
PET's Role in History:
PET has been used for more then just bottles throughout the years. During WWII it was used as a coating for underwater cables. PET's lightweight nature made it a great material to use to insulate radars, which helped to reduce the overall weight.
