    Product Features

    Extrusion board performance characteristics:
    1, thermal insulation
    The extruded board has the characteristics of high thermal resistance, low linearity and low expansion ratio. The closed cell ratio of the structure is over 99%, forming a vacuum layer to avoid air flow and heat dissipation, ensuring its thermal insulation performance.
    2, high strength and pressure resistance
    Due to the special structure of XPS board, it has high compressive strength and strong impact resistance. According to the different types and thicknesses of XPS, its compressive strength reaches 150~500Kpa, it can withstand the ground load of each system, and it is applied to geothermal engineering, highway, Airport runway, plaza floor, large cold storage and interior decoration and insulation.

    3, drowning, moisture resistance
    Water absorption is an important parameter for measuring insulation. After the water absorbing material absorbs water, the heat preservation performance decreases. At low temperature, the inhaled water is easy to freeze, which destroys the structure of the heat insulating material, thereby lowering the compressive and heat insulating properties of the plate. Since the molecular structure of polystyrene itself does not absorb water, the molecular structure of XPS extruded board has no gap, which solves problems such as water leakage, penetration, frosting and condensation of other materials.
    4, light texture, easy to use
    The closed-cell foaming chemical structure of XPS extruded board and its honeycomb physical structure make it light and high-strength, easy to cut and transport, and not easy to break and easy to install.
    5, good corrosion resistance
    In the long-term use, the xps extruded board does not age, does not decompose, does not produce harmful substances, does not cause degradation due to water absorption and corrosion, and its performance is degraded, and can maintain its performance under high temperature environment. According to relevant information, XPS The extruded insulation board is used for 30 to 40 years, and no decomposition or mildew occurs, and no toxic substances are volatilized.

     

    Product Usage

    Extruded Polystyrene (XPS) Insulation board is a kind of rigid extruded polystyrene thermal insulation material, having a smooth surface to prevent the formation of thermal bridges. 
    Due to its excellent property of Thermal Resistance, it is widely applied in areas such as Roof Insulation, Wall Insulation, Floor Insulation, Swimming Pools, Heavy Industrial Floor, Cold Storage, Ice Rink Base, Logistic Truck Manufacturing as well as High Speed Railway Base.
