hermal insulation
With the characteristics of high thermal resistance, low linearity and low expansion ratio, its structure has a closed-hole ratio of more than 99%, forming a vacuum layer, avoiding air flow and
heat dissipation, and ensuring the durability and stability of its thermal insulation performance. Compared with the 80% closed-hole ratio of foaming polyurethane, its leading advantage is really
obvious. Practice has proved that 20mm thick XPS extrusion insulation board, its insulation effect is equivalent to 50mm thick foam polystyrene, 120mm thick cement perlite. Therefore, this
material is the best choice for building heat insulation.
2. High compressive strength
Due to the special structure of XPS plate, its compressive strength is extremely high and its impact resistance is extremely strong. According to the different models and thickness of XPS, its
compressive strength can reach more than 150 ~ 500Kpa, and it can withstand various systems of the ground load. It is widely used in geothermal engineering, expressway, airport runway, square
ground, large cold storage and interior decoration insulation and other fields.
3. Hydrophobic, moisture-proof
Water absorption is an important parameter to measure thermal insulation material. After absorbing water, the thermal insulation performance of the thermal insulation material decreases. In the
case of low temperature, the water inhaled is easy to freeze, which destroys the structure of the thermal insulation material, thus reducing the compressive resistance and thermal insulation
performance of the plate. Because polystyrene molecular structure itself does not absorb water, plate molecular structure is stable, no gap, solving other materials leakage, infiltration, frost,
condensation and other problems.
