Properties of polystyrene foam board

 

The extruded polystyrene insulation board (XPS) has a thermal conductivity of 0.028 W/(m.k), which is far lower than other insulation materials. It has good thermal insulation properties, and has stable chemical structure, physical structure (to ensure long-lasting and stable thermal insulation performance) and linear linear expansion rate. It is one of the best building thermal insulation materials.The extruded polystyrene insulation board has a completely closed cell foam structure to form a uniform honeycomb structure with good hardness, but is not as brittle as polyurethane foam and phenolic foam material. The compressive strength under deformation is 150 to 700 kPa.

Therefore, it is not easy to be broken, not only is it easy to carry and install, but it is easy to cut, and it is used for roof insulation without affecting the load-bearing capacity of the structure. Since the foamed structure of the extruded polystyrene insulation board (XPS) is closely connected and there is no gap between the walls, the impact strength is extremely high, and the foaming remains unchanged even after prolonged foaming. Therefore, it is used as a parking platform, an airport runway, a highway, etc., and it is officially utilized for its good impact resistance.
