    Frequently Asked Questions

    Q What is the heat conductivity coefficient of this extruded polystyrene foam 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), indicating excellent thermal insulation performance.
    Q What compression strength does this XPS foam sheet achieve?
    The product achieves a compression strength of 550 kPa, significantly exceeding the minimum standard requirement of ≥250 kPa, making it suitable for high-load applications.
    Q How does the water absorption rate of this foam sheet compare to the standard?
    The tested water absorption rate is only 0.8%, well within the standard limit of ≤1.5%. This low water absorption helps maintain long-term thermal insulation efficiency and structural integrity.
    Q Is the dimensional stability of this product reliable for construction use?
    Yes. The dimensional stability is tested at 0.12%, far below the standard threshold of ≤0.3%. This ensures the sheets maintain their shape and size under varying temperature and humidity conditions, making them highly reliable for construction applications.
    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 the standard requirements, confirming the product's high quality and reliability.
    Q 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, floors, and foundations. Their excellent thermal resistance, high compressive strength, and low water absorption make them ideal for both residential and commercial construction projects.
