🔬 Scientific Definition

Polyethylene (PE) is a thermoplastic polymer derived from the polymerization of ethylene monomers ((C_2H_4)).

  • Chemical Formula: ((C_2H_4)_n)
  • Production Method: Polymerization using catalysts such as Ziegler–Natta or metallocenes, which control molecular weight and branching.
  • Source: Primarily produced from petroleum and natural gas feedstocks.

Its simple structure and versatile properties make polyethylene the backbone of the global plastics industry.

đź“Š Types of Polyethylene

Type Characteristics Applications
LDPE (Low-Density Polyethylene) Flexible, transparent, low tensile strength Plastic bags, food packaging films
HDPE (High-Density Polyethylene) Rigid, strong, resistant to chemicals Bottles, pipes, household containers
LLDPE (Linear Low-Density Polyethylene) High tensile strength, puncture resistance Industrial packaging, agricultural films
UHMWPE (Ultra-High Molecular Weight Polyethylene) Exceptional toughness, wear resistance Medical implants, lightweight armor
