China Extruded Polystyrene Foam Plastic Sheet - High-Quality Insulation Board from Trusted Suppliers and Factory

Extruded polystyrene foam plastic sheets are high-performance insulation boards manufactured from polystyrene resin through advanced extrusion molding processes. With a closed-cell structure and a closed-cell rate exceeding 90%, these sheets offer superior insulation compared to traditional foam materials. They are designed for exceptional compressive strength, ensuring they resist deformation and collapse under pressure. Our products are ideal for a wide range of applications, including exterior wall insulation, basement moisture prevention, bathroom waterproofing, and highway sub-grade insulation. As a leading manufacturer and supplier in China, our factory is committed to delivering top-quality foam insulation solutions tailored to meet the needs of our customers

    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 product compare to the standard requirement?
    The tested compression strength is 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 long-term moisture resistance and durability.
    Q
    Does the product meet dimensional stability standards?
    Yes. The dimensional stability test result is 0.12%, far below the standard requirement of ≤0.3%. This ensures the product maintains its shape and size under varying temperature and humidity conditions.
    Q
    Has the extruded polystyrene foam plastic sheet passed all required tests?
    Yes. The product has passed all four key performance tests — heat conductivity coefficient, compression strength, water absorption, and dimensional stability — all results meeting or exceeding the standard requirements.
    Q
    What are the typical applications of extruded polystyrene foam plastic sheets?
    Extruded polystyrene (XPS) foam sheets are widely used in building insulation, including roofing, floor insulation, exterior wall systems, cold storage, and civil engineering projects, thanks to their outstanding thermal performance, high compressive strength, and low moisture absorption.
