Polyolefin
Mandarin:
聚烯烃 (jù xī tīng)
聚烯烃 (jù xī tīng)
Explanation in English Language (EN):
A polyolefin is a type of polymer derived from an olefin (alkene) monomer. Olefins are hydrocarbons containing a carbon-carbon double bond. Common examples of polyolefins include polyethylene (PE), polypropylene (PP), and polystyrene (PS). Polyolefins are widely used in various applications due to their low cost, good mechanical properties, and ease of processing. They are found in packaging, films, fibers, and many other products.
