Polyethylene (PE)

Polyethylene is one of the most common and widely used thermoplastics. It’s available in different grades, primarily Low-Density Polyethylene (LDPE), High-Density Polyethylene (HDPE), and Linear Low-Density Polyethylene (LLDPE). It is known for its flexibility, durability, and resistance to chemicals and moisture. It can be processed easily by extrusion or molding.

  • Density: LDPE (0.91–0.93 g/cm³), HDPE (0.94–0.97 g/cm³), LLDPE (0.91–0.94 g/cm³)
  • Melting Point: LDPE (105–115°C), HDPE (120–130°C)
  • Tensile Strength: LDPE (8–14 MPa), HDPE (25–30 MPa)
  • Flexibility: Good flexibility in LDPE and LLDPE, rigid in HDPE
  • Chemical Resistance: Excellent resistance to acids, alcohols, and bases

Packaging: Plastic bags, shrink films, and food packaging, Containers: Bottles, jars, and closures, Industrial: Pipes, geomembranes, and liners.
