Description
This polyurethane foam core sandwich panel is a high-performance insulation panel designed for mobile cold storage, refrigerated trucks, portable refrigeration units, and other temperature-controlled applications. The panel utilizes a durable FRP (fiber reinforced plastic) skin and a polyurethane (PU) foam core, effectively balancing lightweight construction, strength, and insulation performance.
Product Features
- Lightweight.
- Thermal insulation.
- Waterproof and moisture-proof.
- Low-temperature resistant.
Panel Structure Composition
- Compared to traditional steel or aluminum skin sandwich panels, the FRP skin has a lower density and lower thermal conductivity, helping to reduce heat transfer through the panel. Therefore, FRP skin polyurethane foam sandwich panels are particularly suitable for cold storage applications requiring stable internal temperatures and minimal refrigeration energy consumption.
- The polyurethane foam core, with its closed-cell structure and low thermal conductivity, provides excellent insulation performance. Combined with the FRP skin, the panel forms a highly efficient insulation barrier, helping to maintain low temperatures while reducing the overall weight of the insulation structure.
