Ipiranga Petrochem HC 7260 LS HDPE
Categories: Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE); High Density Polyethylene (HDPE), Injection Molded

Material Notes: IPQ produces High Density Polyethylene (HDPE) for use by different segments of the plastics molding industry in several processes, including blow molding, extrusion and injection molding.

To produce HDPE, IPQ employs Hoechst/Hostalen technology through the following steps: the ethene supplied by COPESUL is processed by Ipiranga Petroquímica in reactors to produce powdered polyethylene. The polyethylene then receives additives and is homogenized with stabilizers and taken to extruding presses where it is granulated and is ready for marketing.

An integrated and computerized system controls the production, from the initial processing stages to end-product testing for later commercialization.

Applications:

  • buoys for pool lanes
  • crates
  • hard hats
  • pallets
  • shipping crates
  • stackable crates
