What are HDPE and LLDPE?

  • HDPE: Iran High-density polyethylene (HDPE) is one of the most commonly used plastics in across the world. Iran HDPE is a polyethylene thermoplastic made from petroleum and its recycling code is 2. (#2 plastic Label)
  • LLDPE: Iran Linear Low Density Polyethylene (LLDPE) is a linear polymer (polyethylene) that is a thermoplastic made from the polymer of ethylene and another longer olefin. Iran LLDPE has a significant number of short branches so they can slide against each other upon elongation without becoming entangled .It is marked with the resin and its recycling code is 4. (#4)

What are Difference between Iran petrochemical co HDPE and LLDPE?

1. Iran HDPE Special Features

  • stronger than standard polyethylene
  • effective barrier against moisture, insects, rot and other chemicals
  • remains solid at room temperature
  • HDPE melting point more than 20 °C (250 °F)
  • Good impact resistance, light weight, very low moisture absorption, and high tensile strength
  • Good chemical resistance and high rigidity make it a good choice for trays and tanks
  • its Natural color is milky white, semi-translucent depending on density
  • Use it for sturdy products like PE pipe and etc.

2. Iran LLDPE Special Features

  • High flexibility
  • Its natural color is milky with relative transparency
  • Its melting point is about 110 °C (230 °F)
  • Excellent resistance against acids, bases and vegetable oils Dilute
  • Relative transparency and almost unbreakable.
  • Cheaper than other products
  • strength against high impact
  • Toxicity lower than other products so use it for food, contact and medical applications
  • Use it widely for water, chemicals and gases
