HDPE Resin
High-Density Polyethylene for Blow Molding, Injection, Pipe, Film and Extrusion Applications
HDPE Resin for Multiple Processing Applications
HDPE combines good stiffness, chemical resistance, moisture resistance and practical processing performance.
Different grades are designed for different production methods, including blow molding, injection molding, pipe extrusion, film extrusion and sheet production.
Blow Molding
HDPE blow-molding grades are available for bottles, jerry cans, household chemical containers, industrial drums and other hollow plastic products.
Injection Molding
Suitable grades can be used for crates, bins, caps, closures, household products, pallets and general industrial injection-molded parts.
Pipes and Fittings
Specialized HDPE pipe grades are used for pressure pipes, water supply systems, gas pipes, drainage pipes, conduits and related fittings.
Film and Liners
HDPE film grades are suitable for shopping bags, garbage bags, industrial liners, packaging films and selected thin-film applications.
Sheet and Geomembrane
Selected extrusion grades are available for HDPE sheets, boards, industrial liners and geomembrane applications requiring durability and chemical resistance.
Monofilament and Tape
Suitable HDPE grades can be used for monofilaments, tapes, ropes, nets, woven products and selected industrial textile applications.
Typical Characteristics of HDPE Resin
HDPE is commonly selected for applications requiring good stiffness, strength, chemical resistance, moisture resistance and dimensional stability.
Its performance varies according to molecular structure, density, melt flow rate, additives and intended processing method. The technical data sheet of the exact grade should always be reviewed before final material selection.
How to Select a Suitable HDPE Grade
The correct HDPE grade depends on the processing method, melt flow rate, density, mechanical requirements, product design and regulatory requirements.

FAQs
HDPE is commonly used for bottles, industrial containers, crates, bins, caps, pipes, films, sheets, geomembranes, household products and other molded or extruded plastic products.
HDPE generally provides higher stiffness and strength, while LDPE offers greater softness and clarity. LLDPE is commonly selected for flexible film applications requiring toughness and puncture resistance.

No. Pressure pipes require specialized pipe grades designed and tested for long-term pressure performance. General injection, film or blow-molding grades should not be used as substitutes.
