Home » Materials » HDPE Composite Panels
Aluminum skin HDPE (High Density Polyethylene) core composite panels are a type of duraplate material that combines the lightweight and durable properties of aluminum with the thermal and mechanical advantages of high-density polyethylene (HDPE) as a core material. Engineered to provide exceptional strength, resilience and insulation, these panels are suitable for a wide range of applications in industries such as construction and transportation.

What is HDPE?
HDPE (High Density Polyethylene) is a thermoplastic polymer made from petroleum. It is one of the most widely used plastics across a wide range of industries due to its excellent strength-to-weight ratio, chemical resistance, and versatility.
Key Features of HDPE:
- High Strength-to-Weight Ratio.
- Chemical Resistance.
- Durability and Toughness.
- Low Moisture Absorption.
- Flexibility.
- Recyclability.

Applications of Aluminum Skin Duraplate for Trucks and Trailers
HDPE ACP panels are the ideal material choice for dry freight truck and trailer manufacturers and operators looking to improve vehicle durability, efficiency and aesthetics.
- Lightweight & High Strength
The combination of aluminum skin and HDPE core provides a high strength-to-weight ratio, which can keep the structure stable during severe vibrations and bumps. It can effectively offset the impact of the box body and other objects, protecting the safety of the cargo inside. - Weathering and Corrosion Resistance
The aluminum skin is UV-resistant, moisture-proof and corrosion-resistant, and its surface is pre-coated (PVDF) making these panels ideal for use in outdoor environments and severe weather conditions, even in coastal or high humidity areas. - Recyclable
Both HDPE and aluminum are recyclable, with a recycling rate of up to 100%, and the difficulty of recycling and reproducing is extremely low, which is conducive to the development of a sustainable economy. - Low Maintenance
The smooth surface of ACP panels is easy to clean and maintain, requiring only minimal maintenance, which can reduce operating costs and increase service life. This is especially important for truck bodies or trailers exposed to dust and debris.
