Commodity Resins
The five main commodity resins are polyethylene (LDPE, LLDPE, HDPE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), and polyethylene terephthalate (PET). Key applications range from flexible and rigid food and non-food packaging, to a broad range of consumer goods products, agricultural and industrial products, automotive, and construction, including pipes.

FAQ: Commodity Resins
Polyethylene is considered a “commodity” material, a designation that gives the impression that not much thought needs to go into picking the correct grade of material. But PE can be remarkably complicated simply because it is the only polymer that is available across a wide range of densities.
