Aluminum PU Sandwich Panels

Aluminum PU sandwich panels are a commonly used thermal insulation composite material. Typically, it consists of two outer layers of aluminum sheets and a core of polyurethane foam (PU). This structure gives the PU sandwich panel lightweight, thermal insulation and fireproof properties.

Basic Structure

  • Aluminum Sheet: Its properties include light weight, corrosion resistance, good electrical conductivity, high plasticity, and high strength.
  • PU Foam: Polyurethane foam is a versatile synthetic material that is lightweight, insulating, corrosion-resistant, earthquake-resistant, heat-insulating, sound-insulating and more.

Product Features

  • Lightweight: Aluminum sheets and PU foam are lightweight and easy to handle and install, reducing construction time and costs.
  • Insulation: Polyurethane foam core provides effective thermal insulation, helping to maintain comfortable indoor temperatures and reduce heating or cooling costs.
  • Weather Resistance: Aluminum flakes on the exterior protect the panel from weather elements such as rain, sun and wind, ensuring durability and longevity.
  • Fire Resistance: PU foam core material can be made into fire-proof materials to ensure safety in the event of fire.
  • Aesthetics: Aluminum PU sandwich panels are available in a variety of designs, colors and finishes, allowing designers and manufacturers to create aesthetically pleasing products.
  • Environmentally Friendly: Aluminum and polyurethane foam can be recycled, making these panels more environmentally friendly than other non-recyclable materials.

Applications

Aluminum PU sandwich panels are widely used in various industries that require thermal insulation.

  • Cold Storage: Due to its excellent thermal insulation properties, aluminum PU sandwich panels are often used on the walls and tops of cold storage, storage rooms and refrigeration facilities to ensure stable internal temperatures and reduce energy consumption.
  • Transportation: Aluminum PU sandwich panels are used in the manufacture of ships, trains, RVs, and box trucks to provide lightweight, high-strength and thermal insulation properties.
  • Building Wall Panels: It is used for interior and exterior wall panels and ceilings of factories, warehouses, offices, hotels, farms and other buildings. It can not only provide structural support, but also has good heat preservation and insulation properties.
