Extrusion board performance characteristics
The advantages of extruded board as a new type of material are too many. What are the advantages and performances of the extruded board? The extruded board has great advantages in terms of heat insulation, pressure resistance, moisture resistance, environmental protection, etc. The following is a brief introduction by everyone.
1.Excellent thermal insulation
It has high thermal resistance, low linearity and low expansion ratio. Its structure has high closed cell ratio and forms a vacuum layer to avoid air flow and heat dissipation, ensuring durability and stability of its thermal insulation performance, and 80% closed cell ratio relative to foamed polyurethane. The advantages are self-evident. Practice has proved that 20mm thick XPS extruded insulation board, its insulation is equivalent to 50mm thick EPS molded polystyrene board, 120mm thick cement perlite. Therefore, this material is a good choice for building insulation.
2.Good strength and high pressure resistance
Due to the special structure of XPS extruded board, its compressive strength is high and its impact resistance is strong. According to the different types and thicknesses of XPS, its compressive strength reaches 150~700Kpa, it can withstand the ground load of each system and is applied to geothermal. Engineering, highways, airport runways, plaza floors, large cold storage and interior decoration and insulation.
3.Good drowning, moisture resistance
Water absorption is an important parameter for measuring insulation. After the water absorbing material absorbs water, the heat preservation performance decreases. At low temperature, the inhaled water is easy to freeze, which destroys the structure of the heat insulating material, thereby reducing the pressure resistance and heat insulating performance of the plate. Since the molecular structure of polystyrene itself does not absorb water, the molecular structure of the plate is stable and has no gap, which solves problems such as water leakage, penetration, frosting and condensation of other materials. Light weight and easy to use, the closed-cell foaming chemical structure of XPS board and its honeycomb physical structure make it light and strong, easy to cut and transport, and not easy to break and easy to install.
4.Stability, corrosion resistance is good
Extrusion board does not age, decompose, or produce harmful substances during long-term use. Its chemical properties are relatively stable, it will not be degraded by water absorption and corrosion, and its performance will be degraded. It can still maintain its high temperature environment. Excellent performance, according to the relevant information, XPS extruded insulation board can maintain excellent performance even if it is used for 30 to 40 years, and will not decompose or mold.
5.Product environmental performance
The XPS extruded board has been tested for its chemical properties and non-volatile hazardous substances. The raw materials used are environmentally friendly materials and do not cause industrial pollution. Therefore, it belongs to environmentally friendly building materials.
