HDPE is a polymer of the family of the olefin polymers (like polypropylene). It is a thermoplastic polymer made of repetitive units of ethylene. It is called HDPE for its English acronym: High-Density PolyEthylene (HDPE) or PolyEthylene High-Density (PEHD). It is used to manufacture recyclable plastic bottles, as well as in many industrial aplications. HDPE is a polymer with a lineal structure, without branching.
