XPS Extrusion board has the characteristics of high thermal resistance, low linearity and low expansion ratio. The closed cell rate of its structure has reached more than 99%, forming a vacuum layer, avoiding air flow and heat dissipation, ensuring its long-lasting and stable thermal insulation performance. Compared with 80% closed cell rate of foaming polyurethane, it has the leading advantage. It has been proved that the insulation effect of 20 mm thick XPS extruded insulation board is equivalent to that of 50 mm thick expanded polystyrene and 120 mm thick cement perlite. Therefore, extruded board is the best choice of floor heating insulation materials.

 

Because of the special structure of XPS extruded plate, its compressive strength is very high and impact resistance is very strong. According to the different types and thickness of XPS, its compressive strength is more than 150-500kpa, which can bear the ground load of each system. Water absorption is an important parameter to measure thermal insulation materials. Because the molecular structure of XPS extruded board is stable and there is no gap, the molecular structure of polystyrene does not absorb water itself, and the thermal insulation performance of the thermal insulation material decreases after absorbing water. Under low temperature, the water inhaled is very easy to freeze, which destroys the structure of the thermal insulation material, so that the compressive and thermal insulation performance of the board decreases, and solves the problems of water leakage, penetration, frost, condensation of other materials.

 

XPS Extrusion board belongs to environmental protection material, which has no industrial pollution, no peculiar smell, long-term use efficiency temperature, no toxicity and no harm. It is the best one of building insulation materials at present.
