1. Excellent thermal insulation performance
It has the characteristics of high thermal resistance, low linearity, and low expansion ratio, and the closed cell rate of its structure has reachedOver 99%, a vacuum layer is formed to prevent air flow and heat dissipation, ensuring the durability and stability of its insulation performance. Compared to the 80% closed cell rate of foamed polyurethane, its advantages are self-evident. Practice has proven that the insulation effect of 20mm thick XPS extruded insulation board is equivalent to that of 50mm thick foamed polystyrene and 120mm thick cement perlite.
2. High strength compressive strength
Due toThe special structure of XPS board has excellent compressive strength and impact resistance. Depending on the different models and thicknesses of XPS, its compressive strength can reach 150-500Kpa or more, and it can withstand ground loads of various systems. It is widely used in geothermal engineering, highways, airport runways, square floors, large cold storage facilities, and interior decoration and insulation of vehicles.
3. Hydrophobicity and moisture resistance
Water absorption rate is an important parameter for measuring insulation materials. After absorbing water, the insulation performance of the insulation material decreases. At low temperatures, the absorbed water is easily frozen, damaging the structure of the insulation material and resulting in a decrease in the compressive strength and insulation performance of the board. Due to the fact that the molecular structure of polystyrene itself does not absorb water, the molecular structure of the board is stable without gaps, solving problems such as water leakage, infiltration, frosting, and condensation in other materials.
4. Lightweight texture and easy to use
The completely closed cell foaming chemical structure and honeycomb like physical structure of XPS board make it lightweight, high-strength, easy to cut, transport, and not easily damaged, and easy to install.
5. Good stability and corrosion resistance
During long-term use, it does not age, decompose, or produce harmful substances. Its chemical properties are stable and will not degrade due to water absorption or corrosion, resulting in a decrease in its performance. It can still maintain its superior performance in high temperature environments. According to relevant information,XPS extruded insulation board can maintain excellent performance even after 30-40 years of use, without decomposition or mold, and without the volatilization of toxic substances.
6. Product environmental performance
The XPS board has been tested by relevant national departments and has stable chemical properties. It does not emit harmful substances and is harmless to the human body. The production materials are environmentally friendly and do not produce any industrial pollution. This product belongs to environmentally friendly building materials.
