Performance characteristics:

1、Heat insulation

With high thermal resistance, low linearity, low expansion ratio, the formation of a vacuum layer, to avoid air flow heat dissipation, to ensure the durability and stability of its thermal insulation performance, relative to the foamed polyurethane 80% of the closed cell rate, the advantages are self-evident. Practice has proved that 20mm thick XPS extruded insulation board, its thermal insulation effect is equivalent to 50mm thick foamed polystyrene, 120mm thick cement perlite. Therefore, this material is currently the choice of building insulation.

2、High-strength compression resistance

Due to the special structure of the XPS board, its compressive strength is very high, impact resistance, according to the different models of XPS and thickness of its compressive strength of 150 ~ 500Kpa or more, can withstand the ground load of the system, widely used in geothermal engineering, highways, airport runways, plazas and ground, large-scale cold storage and car decorative insulation and other fields.

3、Hydrophobic, moisture-proof

Water absorption is an important parameter to measure the thermal insulation material. Insulation materials absorb water after the insulation performance declines, in the case of low temperature, inhaled water is very easy to freeze, destroying the structure of the insulation material, so that the compression resistance of the plate and the decline in thermal insulation performance. As the polystyrene molecular structure itself does not absorb water, the molecular structure of the plate is stable, no gap, solving the problems of water leakage, infiltration, frost, condensation, etc. of other materials.

4、Light weight, easy to use

XPS board's completely closed-cell foaming chemical structure and its honeycomb physical structure, so that it has a lightweight, high-strength properties, easy to cut, transportation, and not easy to break, easy to install.

5、Stability, good anti-corrosion

Long-term use, does not age, does not decompose, does not produce harmful substances, its chemical properties are stable, will not cause degradation due to water absorption and corrosion, etc., so that its performance decline, in the high temperature environment can still maintain its superior performance, according to the information, XPS extruded insulation board even if the use of 30 ~ 40 years, can still maintain excellent performance, and will not decompose or mold, no toxic substances volatile.
