Home > Composites > Fiberglass XPS Foam Sandwich Panels
FRP(fiberglass) XPS foam Sandwich Panel is a sandwich panel made of extruded polystyrene (XPS) foam and FRP. XPS foam has a closed-cell structure and is a low-density hard material that can effectively reduce heat conduction. This composite structure makes the XPS foam FRP Sandwich Panel excellent in thermal insulation, waterproofing, compression resistance, and durability.
We are the top fiberglass XPS foam sandwich panel supplier. We offer design, CNC machining and OEM/ODM customized production. Including: size, thickness, foam density, coating, color, pattern and so on.
- Ultra-lightweight
- Weather resistant
- Ultra-tough
- Durable
Features and Benefits
- Toughness: high compressive strength and resistance to deformation from impact.
- Low thermal conductivity: XPS has low thermal conductivity, 0.03 W/(m·K).
- Low water absorption: 0.1% water absorption, better than EPS and XPS.
- Long service life: the truck body lasts 10 years. The process maintains its performance.
- Wide temp range: -20℃ to 50℃.
- Low cost: we are the source manufacturer of FRP XPS panels, and we have low cost.
- High precision: we use the world’s best CNC machines and production equipment.
- Customizable: Highly customizable.
Structure
FRP Panels
- External layer is a fiberglass layer, which has a flat and smooth surface with no dirty spots. It has extremely high strength and weather resistance, effectively preventing the erosion of external moisture and chemical substances.
- FRP surface has been treated with anti-UV treatment, so it will not fade and maintain its original color for a long time outdoors; it can withstand high temperatures of 80°C without deformation, and withstand low temperatures of -40°C without becoming brittle.
- Add flame retardants and anti-aging agents to increase safety and service life.
XPS Foam Core
XPS foam is a fully recyclable material. It is made from extruded polystyrene, which does not deteriorate. The foam structure consists of very small closed cells, which makes it highly resistant to compression and water-repellent.
Embedded Reinforcement Material
For some applications that require increased strength (such as ambulances and RVs), reinforced structural materials such as wood, aluminum tubes, fiberglass reinforced plastic tubes, and high-strength plastic bars will be embedded inside the fiberglass XPS foam sandwich panels.
