Definition and Structure

Polyethylene (PE) is a high molecular compound polymerized from ethylene monomers. Its molecular chain is primarily composed of carbon and hydrogen atoms, connected by repeating —CH₂—CH₂— units. Depending on the polymerization method and conditions, it can exhibit linear or branched structures.

Classification

• Low-Density Polyethylene (LDPE): Generally polymerized under high temperature and high pressure, it has numerous short branches with a density of 0.910-0.925 g/cm³. It offers good transparency, flexibility, low-temperature resistance, and breathability, commonly used in films, pipes, and other applications.

• High-Density Polyethylene (HDPE): Produced through low-pressure polymerization processes, its molecular chains are tightly arranged with few branches, and its density ranges from 0.941 to 0.965 g/cm³. It exhibits high rigidity, hardness, mechanical strength, and chemical corrosion resistance, widely used in pipes, injection-molded products, and more.

• Linear Low-Density Polyethylene (LLDPE): Formed by copolymerizing ethylene with a small amount of α-olefins under catalyst action, it combines some properties of both LDPE and HDPE. Its linear structure provides better tensile strength, tear resistance, and other properties, primarily used in film production.
