Commodity Plastics
The more commonly used thermoplastic materials are known as commodity plastics as they are traded and used in great quantities. Examples are polystyrene (PS), polyvinyl chloride (PVC), polypropylene (PP) and polyethylene (PE).
Typical applications for commodity plastics are high production volume products such as ‘polythene’ bags (made from polyethylene), vacuum-formed food packaging (low density polyethylene), disposable drinking cups (high-impact polystyrene) and window frames/wire insulation (PVC).

Famous quotes containing the word commodity:
“A commodity appears at first sight an extremely obvious, trivial thing. But its analysis brings out that it is a very strange thing, abounding in metaphysical subtleties and theological niceties.”
—Karl Marx (1818–1883)
