1. Excellent heat preservation and insulation? It has the characteristics of high thermal resistance, low linearity and low expansion ratio. Its structure has a closure rate of more than 99%. It forms a vacuum layer, avoids air flow and heat dissipation, and ensures the long-lasting and stable heat preservation performance. Compared with 80% closure rate of foaming polyurethane, its leading advantage is self-evident. It has been proved that the insulation effect of 20 mm thick XPS extruded insulation board is equivalent to that of 50 mm thick expanded polystyrene and 120 mm thick cement perlite. Therefore, this material is the best choice for building insulation at present. ?
2. Excellent high strength compressive strength? Due to the special structure of XPS board, its compressive strength is extremely high and impact resistance is very strong. According to different types and thicknesses of XPS, its compressive strength reaches over 150-500kpa, which can bear the ground load of various systems. It is widely used in Geothermal Engineering, high-speed roads, airport runways, square ground, large-scale cold storage, interior decoration and heat preservation and other fields. ?
3. High quality hydrophobicity, moisture resistance? Water absorption is an important parameter to measure thermal insulation materials. After absorbing water, the heat preservation performance of the insulation material will decrease. At low temperature, the water inhaled is easy to freeze, which destroys the structure of the insulation material, thus reducing the compression and heat preservation performance of the board. Because polystyrene molecular structure itself does not absorb water, the molecular structure of the plate is stable and there is no gap, which solves the problems of other materials such as water leakage, penetration, frost, condensation, etc. ?
4. Light texture, easy to use? The complete closed cell foaming chemical structure and honeycomb physical structure of XPS board make it light and high strength, easy to cut and transport, not easy to be damaged, and easy to install. ?
5. Good stability and corrosion resistance ? during long-term use, it will not age, decompose or produce harmful substances. Its chemical performance is extremely stable, and it will not degrade due to water absorption and corrosion, which will degrade its performance. It can still maintain its superior performance under high temperature environment. According to relevant data, XPS extruded insulation board can maintain excellent performance even if it is used for 30-40 years, and it will not decompose or mildew , no volatilization of toxic substances. ?
6. Environmental protection performance? XPS board has stable chemical performance, non-volatile harmful substances and is harmless to human body as tested by relevant national departments. Environmental protection materials are used as production raw materials without any industrial pollution. The product belongs to environmental protection building materials.
