HDPE Composite Panels (DuraPlate)

HDPE composite panels are sandwich panels with a high-density polyethylene (PE) plastic core and aluminum or pre-coated steel skin. In many countries, it is also simply referred to as “DuraPlate”. It is characterized by high strength and high hardness.

Product Advantages

• Light and thin: Although HDPE has a higher density, it has a higher strength and sandwich structure, so the thickness can generally be less than 1cm.
• Impact resistance: The surface of HDPE sandwich panels is made of high-strength steel sheets or aluminum sheets, which have excellent impact resistance and can maintain integrity when impacted or impacted, and are not easy to break or deform.
• Corrosion resistance: HDPE is a material with good corrosion resistance, so HDPE sandwich panels can be used for a long time in harsh environments without damage.
• Environmental protection: HDPE is a recyclable material, so HDPE sandwich panels can be recycled and reused after use to reduce the impact on the environment.
• Easy to process: HDPE sandwich panels are easy to process and customize, and can be cut, bent, folded, etc. according to specific needs.

Schematic Diagram

• Facing: Choose different facing materials based on project requirements. Aluminum facings are lighter and more corrosion-resistant; galvanized steel facings are strong and affordable; stainless steel facings are strong, durable and look gorgeous.

• Core: HDPE board has high density (0.941~0.960kg/m³). It has good heat resistance and cold resistance (-50~+90℃), good chemical stability, high rigidity and toughness, and high mechanical strength. And these polypropylene plastics are odorless, non-toxic, and recyclable.
