How Is Hdpe Produced

HDPE is made under controlled conditions by applying intense heat to petroleum. This process, also known as “cracking,” helps create ethylene gas. During its production, the gas molecules will attach to form polymers, which then produce polyethylene.

How are HDPE and LDPE made?

LDPE is produced by compressing monomer ethylene gas in an autoclave or tubular reactor to facilitate polymerization—i.e., the linking of monomers into polymer chains. HDPE is created by heating petroleum to very high temperatures.

Can HDPE be formed?

HDPE can easily be shaped using conventional methods, such as heat bending, pressure forming, and vacuum forming.
