I. Product Introduction and Applications
Expanded polystyrene boards are materials continuously extruded and foamed into shape through special technology. Their surface forms a hard film that is even and flat, with a closed-cell foam structure that is continuous and uniform, resembling a honeycomb. As a result, they possess high compressive strength, lightweight, non-absorbent, impermeable, wear-resistant, and non-degradable properties.
Application: Widely used in various architectural and decorative settings
Section II: Key Features
Compared to EPS polystyrene foam boards, it offers significantly improved strength, thermal insulation, and resistance to moisture vapor penetration. It can maintain its thermal insulation and compressive strength even when submerged, making it particularly suitable for building insulation, thermal preservation, and moisture-proof treatments. It is one of the cost-effective construction materials in today's construction industry.
Insulation performance
Thermal conductivity not exceeding 0.028 W/mK, significantly lower than other insulation materials (materials with a thermal conductivity of less than 0.25 W/mK are commonly used as insulation materials in engineering), thus featuring high thermal resistance and low linear expansion rate. Widely used in roof insulation and heat preservation systems, cold storage facilities, and thermal insulation for both interior and exterior walls.
(2) Absorbency
As a comprehensive thermal insulation material, water absorption rate is a critical technical indicator. High water absorption can degrade the insulation performance. Extruded polystyrene (XPS) boards have a complete closed-cell structure, with no gaps on either side of the board, preventing moisture from seeping in due to leaks, condensation, and freezing/thawing cycles. This effectively blocks the entry of water molecules, thereby preventing the board from aging and ensuring the insulation layer maintains its function over time. Eventually, this could necessitate repairs to the insulation structure. The closed-cell structure of XPS boards effectively prevents the penetration of water molecules (including vapor), even if mechanically damaged during installation. Due to their tight honeycomb structure, XPS boards maintain low water absorption. With the effective blocking of water molecules and their non-hydrophilic nature, aging is almost impossible, making them nearly as long-lasting as the building itself.
(3) Insulation Performance
Low thermal conductivity is a necessary condition for all insulating materials. XPS boards are made from polystyrene (PS), which is well-known as an insulating material. Additionally, the extrusion process creates a tightly closed-cell honeycomb structure, further enhancing its effectiveness in preventing heat conduction.
(4) Compressive Strength
XPS extruded board is a lightweight, high-strength material, with compressive strength exceeding 350KPa even at densities not exceeding 40kg per cubic meter. Its use in buildings provides excellent impact resistance. The compressive properties of XPS are almost unchanged even when soaked in water, a feature not found in other insulation materials.
(5) Flame Retardant
We offer standard and flame-retardant types to meet the flame-retardant requirements of thermal insulation products for factory buildings, sports venues, convention centers, etc.
(6) High-quality eco-friendly products
XPS extruded boards have stable chemical properties, no volatile harmful substances, and will not decompose or mildew, exhibiting excellent corrosion resistance.
During the production of XPS extruded boards, environmentally friendly materials are used, ensuring no harmful gases are emitted. The production process also embodies green concepts, with solid waste generated being recyclable and reusable, making it an environmentally friendly, recyclable product.
(7) Easy construction with low cost
Due to its lightweight nature, handling is easy, cutting is simple, no electric saw is needed, and installation is straightforward, requiring only iron sheets, wires, plastic adhesives, or polymer mortar to secure. This significantly reduces construction costs.
