PU foam core material, also known as polyurethane foam core, is a rigid structural foam widely used in sandwich panels and insulation systems. It is produced through a chemical reaction between polyols and isocyanates, creating a closed-cell foam structure.
PU foam cores are valued for their excellent thermal insulation properties, low density, and good mechanical strength. In addition to structural support, they provide effective thermal resistance, which makes them suitable for applications requiring insulation.
This material is commonly used in refrigerated truck panels, cold storage panels, building insulation panels, and composite sandwich panels used in industrial construction.
PU foam cores can be manufactured in different density grades depending on the desired balance between structural strength and insulation performance. Higher-density polyurethane foams are used for structural sandwich panels, while lower-density foams are commonly used for insulation applications.
Because of their versatility, PU foam cores remain an important material in both construction and composite panel industries.
