HDPE

High Density Polyethylene(HDPE) is a cost-effective thermoplastic with linear structure and no or low degree of branching. It is manufactured at low temperature (70-300°C) and pressure (10-80 bar) & derived from either:

  • Modifying natural gas (a methane, ethane, propane mix) or
  • The catalytic cracking of crude oil into gasoline 


HDPE is produced majorly using two techniques: Slurry Polymerization or Gas Phase Polymerization.

Applications of High Density Polyethylene (HDPE)

Excellent combination of properties makes HDPE an ideal material in diverse applications across industries. It can be engineered according to the end use requirements.

HDPE in Packaging and Consumer Good ApplicationsSome of the major uses of high density polyethylene include:

  1. Packaging Applications – High Density Polyethylene is used in several packaging applications including crates, trays, bottles for milk and fruit juices, caps for food packaging, jerry cans, drums, industrial bulk containers etc. In such applications HDPE provides the end product a reasonable impact strength.
  2. Consumer Goods – Low cost and easy processability make HDPE a material of choice in several household/ consumer goods like garbage containers, housewares, ice boxes, toys etc.
  3. Fibers and Textiles – Thanks to its high tensile strength, HDPE is widely used for agricultural applications ,  such as in ropes, fishing and sport nets, nets as well as industrial and decorative fabrics.
