Excellent hydrophobicity and moisture resistance.
High-quality floor heating extruded insulation board must have good moisture-proof performance. Water absorption is an important parameter to measure thermal insulation materials. After water absorption, the thermal insulation performance of thermal insulation materials decreases. At low temperature, the absorbed water is easy to freeze, destroying the structure of thermal insulation materials, thus reducing the compressive strength and thermal insulation performance of the board.
Excellent thermal insulation performance
High-quality floor heating extruded insulation board should have a high closed-cell rate and form a vacuum layer to avoid air flow and heat dissipation and ensure the durability and stability of its insulation performance. A large number of practices have proved that the insulation effect of 20mm thick XPS extruded insulation board is equivalent to that of 50mm thick expanded polystyrene and 120mm thick cement perlite.
Good stability and corrosion resistance.
High-quality floor heating extruded insulation board should be used for a long time, without aging, decomposition and harmful substances. Its chemical properties should be stable and not degraded by water absorption and corrosion, and it can still maintain its superior performance under long-term high temperature environment.
