XPS Sandwich Panels

XPS Sandwich Panels

Composite Panel Manufacturer in China

Home » Materials

XPS sandwich panels are a type of composite panel consisting of an extruded polystyrene (XPS) foam core sandwiched between two layers of facing materials. These panels are known for their excellent thermal insulation, lightweight properties, high compressive strength, moisture resistance, and durability.

  • Thermal Insulation
    XPS foam cores offer excellent heat resistance, making them ideal for energy efficiency applications.
  • Lightweight
    XPS foam has a low density and is lightweight, making XPS foam sandwich panels easy to handle, transport, and install.
  • High Compressive Strength
    XPS foam has strong compressive resistance, making the panels suitable for load-bearing applications.
  • Waterproofing
    XPS foam has a closed-cell structure that prevents water absorption, making the panels highly moisture-proof and waterproof.
  • Durability
    XPS foam is not prone to rot or deformation, and has a long service life and stable performance.

How to Improve the Performance of XPS Sandwich Panels

In addition to the selection of high-quality materials and advanced composite technology, the scientific design of TOPOLOGROUP has greatly improved the performance of XPS foam sandwich panels.

  • Pre-embed structural materials in XPS foam as a “skeleton” to enhance its structural strength. These materials include glass fiber profiles, waterproof wood, aluminum tubes, sheet metal, etc.
  • Add energy-absorbing materials between the foam and the surface to enhance its impact resistance.
  • XPS foam can be combined with other materials such as PET foam, PVC foam, plywood, etc. as a core material to improve the performance of sandwich panels.

Advanced Processing Technology

  • Laser positioning ensures the accuracy of sandwich panels.
  • Automatic glue spraying ensures uniform distribution of adhesive.
  • Vacuum high-pressure composite ensures the bonding strength of sandwich panels.
  • CNC machining completes the processing of complex shapes.

Applications

XPS sandwich panels are used in a variety of industries that require insulation, lightweight construction and durability, including construction, refrigeration, transportation and marine applications.

  • Box truck bodies such as refrigerated trucks, dry cargo trucks, ambulances, horse trailers, etc.
  • RV bodies.
  • Modular and prefabricated buildings, such as mobile toilets, capsule rooms, mobile offices, etc.
  • Cold rooms.
  • Clean rooms.
  • Greenhouses.
  • Animal shelters.
  • Farms.
  • Ship interiors.
  • Home decoration.
  • Industrial equipment housings.
