    ❓ Frequently Asked Questions
    Q What is the heat conductivity coefficient of the extruded polystyrene foam plastic sheet?
    The tested heat conductivity coefficient is 0.024 W/(m·K), which is well below the standard requirement of ≤0.030 W/(m·K), demonstrating excellent thermal insulation performance.
    Q How does the compression strength of this XPS sheet compare to the standard requirement?
    The product achieves a compression strength of 550 kPa, which significantly exceeds the minimum standard requirement of ≥250 kPa, making it highly suitable for load-bearing insulation applications.
    Q What is the water absorption rate of the extruded polystyrene foam sheet?
    The water absorption rate is 0.8%, which is well within the standard limit of ≤1.5%. This low absorption rate ensures the product maintains its insulating properties even in moist environments.
    Q Is the dimensional stability of this foam sheet reliable for construction use?
    Yes. The dimensional stability test result is 0.12%, far below the standard requirement of ≤0.3%. This ensures the sheets maintain their shape and size under varying temperature and humidity conditions.
    Q Has this extruded polystyrene foam sheet passed all required quality tests?
    Yes. All four key performance indicators — heat conductivity coefficient, compression strength, water absorption, and dimensional stability — have passed testing and meet or exceed the required standards.
    Q What are the typical applications of extruded polystyrene foam plastic sheets?
    Extruded polystyrene (XPS) foam sheets are widely used in building insulation, including roof insulation, floor insulation, basement walls, cold storage facilities, and other applications that require high thermal resistance, moisture resistance, and structural stability.
