 1, the extruded sheet excellent thermal insulation 
 Extruded plates with high thermal resistance and low linear expansion ratio and low, the structure of the cell rate reached 99%, and the formation of a vacuum layer, to avoid cooling air flow to ensure lasting insulation performance and stability, as opposed to hair 80% closed-cell polyurethane foam rate, leading edge self-evident. XPS proved 20mm thick extruded insulation board, the insulating effect equivalent to 50mm thick polystyrene foam, 120mm thick cement perlite. Therefore, this material is the best choice for building insulation. 
 2, high-strength extruded sheet excellent resistance to stress 
 XPS board XPS board because the special structure of its high compressive strength, impact resistance, strong, according to different models of XPS and thickness of its compressive strength 150 ~ 500Kpa above, the system can withstand the floor loading is widely used in geothermal projects, highways, airport runways, the square on the ground, and the interior decoration of large cold storage insulation and other fields. 
 3, the extruded sheet quality water-repellent, moisture resistance 
 Extruded insulation board is a measure of water absorption is an important parameter. After absorbing insulation material insulation properties fall, at low temperatures, inhalation of water can easily freeze, damage to the structure of the thermal insulation material, so that the compression plate and insulation performance. As the molecular structure of polystyrene itself does not absorb water, sheet molecular structure and stability, without gaps, solve other materials leaking, penetration, frost, condensation and other issues.
