    ❓ Frequently Asked Questions
    💡 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 significantly lower than the standard requirement of ≤0.030 W/(m·K), indicating excellent thermal insulation performance.
    💡 How does the compression strength of this XPS sheet compare to the standard requirement?
    The product achieves a compression strength of 550 kPa, which is more than double the minimum standard requirement of ≥250 kPa, making it highly suitable for load-bearing insulation applications.
    💡 Is the extruded polystyrene foam sheet resistant to water absorption?
    Yes. The water absorption rate is only 0.8%, well below the standard limit of ≤1.5%. This low absorption rate ensures the product maintains its insulating properties even in humid or wet environments.
    💡 What does dimensional stability mean and how does this product perform?
    Dimensional stability refers to the material's ability to maintain its shape and size under varying temperature and humidity conditions. This product records 0.12%, far below the ≤0.3% standard, ensuring reliable long-term performance without warping or shrinkage.
    💡 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 been tested and officially determined as "Pass," meeting or exceeding industry standards.
    💡 What are the typical applications of extruded polystyrene foam plastic sheets?
    Extruded polystyrene (XPS) foam sheets are widely used in building insulation for roofs, walls, and floors, as well as in cold storage facilities, road and railway construction, and other applications requiring superior thermal insulation, moisture resistance, and structural strength.
