Extruded polystyrene board (XPS board), as a high-performance insulation material, its main features can be explained in detail and professionally from multiple aspects such as material performance, physical properties, and application advantages:1. Excellent thermal insulation performanceLow thermal conductivity: Extruded polystyrene board has an extremely low thermal conductivity, usually in the range of 0.024~0.035 W/(m·K), which means that it can effectively prevent the transfer of heat, thereby playing a significant energy-saving effect in building insulation.Closed-cell structure: Its unique closed-cell structure greatly limits air convection and heat conduction, further enhancing the insulation effect.2. High strength and pressure resistanceHigh compressive strength: Compared with other insulation materials such as expanded polystyrene (EPS), extruded polystyrene board has higher compressive strength, can withstand larger loads without deformation, and is suitable for load-bearing occasions such as roofs and parking lots.Good dimensional stability: During long-term use, XPS board can maintain good dimensional stability and is not easy to deform or crack.3. Excellent moisture-proof and waterproof performanceLow water absorption: The water absorption rate of extruded polystyrene board is extremely low and almost no water is absorbed, so it can effectively prevent moisture penetration and keep the building structure dry.Strong anti-freeze and thaw performance: Even under low temperature or freeze-thaw cycle conditions, XPS board can maintain good physical properties and will not be damaged by water freezing and expansion.4. Excellent weather resistance and corrosion resistanceGood chemical stability: Extruded polystyrene board has good corrosion resistance to most acids, alkalis and other chemical substances, and can maintain stable performance in a variety of environments.Long-term use without aging: Its molecular structure is stable and is not easily affected by environmental factors such as ultraviolet rays and oxygen, thus ensuring a long service life.5. Environmental protection and recyclabilityEnvironmentally friendly materials: Extruded polystyrene board has little impact on the environment during production and use, and can be recycled and reused after disposal, which is in line with the concept of sustainable development.No release of harmful substances: During use, XPS board will not release gases or substances that are harmful to the human body, ensuring the health of the indoor environment.6. Convenient and efficient constructionLightweight and easy to cut: Extruded polystyrene boards are light, easy to carry and install, and can be easily cut into various shapes and sizes as needed to meet different construction needs.Strong adhesion: It has good adhesion with a variety of adhesives and plaster mortars, and is easy to firmly combine with base materials such as walls and roofs.Extruded polystyrene boards have been widely used and recognized in the field of building insulation for their excellent thermal insulation performance, high strength and pressure resistance, moisture and waterproof performance, weather resistance and corrosion resistance, environmental protection and recyclability, as well as convenient and efficient construction.
