Overview
The 32 kg/m³ extruded polystyrene (XPS) board is a high-density foam insulation material produced through an extrusion process. It is known for its closed-cell structure, which provides superior thermal insulation and moisture resistance compared to other foam boards. XPS boards are widely used in construction for their durability and ability to withstand heavy loads. The 32 kg/m³ density variant offers an optimal balance between strength and insulation performance, making it suitable for both residential and commercial applications.
Physical and Chemical Properties
The 32 kg/m³ XPS board exhibits a closed-cell structure with a density of 32 kilograms per cubic meter, providing excellent compressive strength (typically 250-500 kPa). Its thermal conductivity ranges from 0.028 to 0.034 W/(m·K), making it highly effective for insulation. The material is chemically inert, resistant to water absorption (less than 1% by volume), and stable under most environmental conditions. It does not rot or degrade easily, ensuring long-term performance in construction applications.
Main Applications
The primary use of 32 kg/m³ XPS boards is in building insulation, particularly for roofs, walls, and floors. Its high compressive strength makes it ideal for inverted roofs, green roofs, and cold storage facilities. It is also used in civil engineering projects, such as road and railway construction, where thermal insulation and load-bearing capacity are critical. Additionally, XPS boards are employed in refrigeration units and as insulation for pipelines.
Safety and Storage
XPS boards are generally safe to handle but should be stored in a dry, well-ventilated area away from direct sunlight and heat sources. Prolonged exposure to UV rays can degrade the material's surface. When cutting or machining XPS, it is advisable to wear protective gear to avoid inhaling dust particles. The material is flammable and should be kept away from open flames or high-temperature environments.
B2B Procurement Guide
When procuring 32 kg/m³ XPS boards, buyers should verify the material's density, thermal conductivity, and compressive strength to ensure it meets project requirements. Certifications such as ISO 9001 and CE marks indicate compliance with quality standards. Prices vary based on thickness, quantity, and supplier. Bulk purchases often attract discounts. It is recommended to request samples and test reports before placing large orders to confirm product quality.
