Chemical and Physical properties:
Polyethylene Terephthalate (PET) is highly flexible, colorless, it can be semi-rigid to rigid. It is semi-crystalline (has a highly ordered molecular structure with sharp melt points) resin in its natural state. Resistance to impact, moisture, alcohols, and solvents. Very strong and lightweight. PET has excellent electrical insulating properties. It is recyclable transparent to microwave radiation. It has a melting point of 240-270 degrees C.
History of the compound:
It was first polymerized in the 1940s by DuPont chemists seeking an ideal material for textile fibers. In 1973, the first PET bottle was patented. In 1977, the first PET bottle was recycled.
