Reasons for choosing XPS foam as core material
Excellent thermal insulation performance
XPS foam has a very low thermal conductivity, generally between 0.020-0.035 W/(m・K), which can effectively block heat transfer and maintain a stable temperature inside the product.
Extremely lightweight
XPS foam has a low density, usually less than 50kg/m³. Due to its light weight and the thin skin materials, XPS foam sandwich panels are easy to handle, transport and install.
High Compressive Strength
The special closed-cell structure of XPS foam gives it extremely strong compressive strength, generally exceeding 400 kPa. Compared to other brittle foam core composite panels, it can withstand greater loads.
Excellent waterproof and moisture-proof performance
XPS foam has a closed-cell structure, resulting in extremely low water absorption, virtually eliminating any water absorption. Even prolonged immersion in water will not deteriorate or rot. Its stable performance prevents water absorption, which can lead to reduced insulation performance and structural damage to the composite board.
Good fire resistance
By adding flame retardants, XPS foam can achieve a fire resistance rating of B1 (hard to burn), which can slow the spread of fire to a certain extent.
