Extruded board performance characteristics

1, excellent thermal insulation
With high thermal resistance, low linear, low expansion ratio, the structure of the closed porosity reached more than 99%, forming a vacuum layer, to avoid air flow heat dissipation, to ensure the durability and stability of its insulation performance, compared with the foam polyurethane 80% of the closed porosity, the leading edge is self-evident. Practice has proved that the 20mm thick XPS extruded thermal insulation board, its thermal insulation effect is equivalent to 50mm thick foamed polystyrene, 120mm thick cement perlite. Therefore, this material is currently the best choice for building insulation.

2, excellent high strength compression resistance

Due to the special structure of XPS board, its compressive strength is extremely high and impact resistance is extremely strong. According to different types and thickness of XPS board, its compressive strength reaches more than 150 ~ 500Kpa, and it can withstand the ground load of various systems. It is widely used in geothermal engineering, expressway, airport runway, square ground, large cold storage and interior decoration insulation and other fields.

3, high-quality hate water, moisture-proof

Water absorption is an important parameter to measure thermal insulation material. After absorbing water, the heat preservation performance of the heat preservation material decreases accordingly. At low temperature, the water inhaled is easy to freeze, which damages the structure of the heat preservation material and thus reduces the compressive strength and heat preservation performance of the plate. Because polystyrene molecular structure itself does not absorb water, plate molecular structure is stable, no gap, solve other material leakage, infiltration, frost, condensation and other problems.

4, light texture, easy to use

XPS board of completely closed cell foaming chemical structure and its honeycomb physical structure, so that it has light, high strength characteristics, easy to cut, transport, and not easy to damage, easy to install.

5. Good stability and corrosion resistance

In use for a long period of time, not aging, don’t break down, do not produce harmful substances, chemical performance is very stable, not as a result of absorbing water and corrosion degradation, make its performance, under the environment of high temperature can still maintain its superior performance, according to relevant data, XPS extruded thermal insulation boards even using 30 ~ 40 years, still can maintain the outstanding performance, and won’t decompose or mildew, no volatile toxic substances.

6. Environmental performance

XPS board by the state departments concerned detection chemical performance is stable, do not volatilize harmful substances, harmless to human body, the production of raw materials using environmentally friendly materials, do not produce any industrial pollution. This product belongs to environmental protection building materials.
