XPS Foam FRP Sandwich Panels

XPS foam fiberglass sandwich panel combines the characteristics of XPS (extruded polystyrene) foam and FRP (fiberglass reinforced plastic), providing excellent performance, it is lightweight, thermal insulation, waterproof, aesthetic, easy to clean, affordable. It is widely used in various industries that require thermal insulation.

Lightweight

Low density greatly reduces the load on the carrier.

Thermal insulation

Low thermal conductivity, blocking heat and cold transfer, and maintaining the temperature inside the panel for a long time.

Waterproof

The surface FRP is not easy to adhere to moisture, and the internal XPS foam does not absorb water. It is suitable for various humid and high-salt environments.

Aesthetics

Its surface is flat and smooth gel-coated FRP, showing an attractive visual effect, and there are multiple colors and patterns to choose from.

Easy to clean

The surface stains can be easily cleaned with water or cleaning fluid.

Details

FRP sheet is a mixture of resin matrix and glass fiber. Its thickness, color, surface treatment, etc. can be customized according to needs.

  • The surface of FRP is treated with UV protection.
  • Flame retardant is added to FRP.
  • Alkali-free glass fiber is used as the reinforcement material of FRP.

MORE

XPS foam is a lightweight closed-cell foam with excellent properties in all aspects and is ideal for manufacturing high-performance composite panels.

  • Thermal conductivity: 0.025-0.035W/m·K.
  • Compressive strength: 200-700 kPa.
  • Tensile strength: 500–1000 kPa.
  • Water absorption: less than 0.5%.

Production and Processing

We are the leading foam sandwich panel manufacturer in China, and with years of industry expertise, we offer a wide range of high-quality sandwich panels to meet the various needs of our customers. Our factory is equipped with industry-leading composite panel production lines, using advanced technology and innovative production techniques to ensure excellent performance and precision. We pride ourselves on our ability to provide customized services, working closely with our customers to provide custom solutions that meet their specific design and functional requirements. Whether you need panels for construction, transportation or other applications, we are committed to providing reliable, efficient and cost-effective solutions to meet your needs.

  • One-piece vacuum composite process: The sandwich panels are formed under high pressure in a vacuum environment to ensure a flat surface, tight bonding, and strength far exceeding that of ordinary composite panels.
  • Excellent size customization: Our composite panels can be manufactured in a maximum size of 12m x 3.2m, which is consistent with the current largest container size of 40 feet (12.03 meters).
  • Customizable shapes: Using high-precision CNC processing, we can manufacture panels of any shape to meet personalized design requirements while maintaining consistent product accuracy and quality.

We also provide FRP sandwich panels with PU (Polyurethane), PET (Polyethylene Terephthalate), and PVC (Polyvinyl Chloride) foam cores. For more information on composite panels, please consult us.
