html  ; Extruded plate 1 (performance introduction) 1
It has the characteristics of thermal insulation, low thermal resistance, low linearity and low expansion ratio
It forms a vacuum layer to avoid air flow and heat dissipation and ensure the long-term and stability of its thermal insulation performance
2
Due to the special structure of XPS board, its compressive strength reaches more than 150 ~ 500kPa according to different models and thickness of XPS, and can bear the ground load of each system
* * * is applied to geothermal Engineering, expressway, airport runway, square ground, large cold storage and interior decoration and thermal insulation, etc 3
Hydrophobicity, moisture resistance and water absorption are important parameters to measure thermal insulation materials
After the thermal insulation material absorbs water, the thermal insulation performance decreases
At low temperature, the inhaled water is very easy to freeze, damaging the structure of the thermal insulation material, so as to reduce the compression and thermal insulation performance of the plate
Because the molecular structure of polystyrene itself does not absorb water, the molecular structure of the plate is stable and has no gap, which solves the problems of water leakage, penetration, frosting and condensation of other materials
4
Light texture and easy to use
The fully closed cell foaming chemical structure and honeycomb physical structure of XPS board make it light and high-strength, easy to cut and transport, not easy to damage and easy to install 5
Stability, anti-corrosion, no aging, decomposition and harmful substances during long-term use, stable chemical properties, no degradation due to water absorption and corrosion, and can maintain its performance under high temperature environment
According to relevant data, XPS extruded insulation board will not decompose or mildew even after 30 ~ 40 years of use, No volatilization of toxic substances 6
The product has environmental protection performance
XPS board has been tested by relevant departments to be chemical, non-volatile and harmful substances and harmless to human body
The production raw materials are environmental friendly materials
