Expanded polystyrene EPS insulation board
Features:
1, Exnt thermal insulation performance
Polystyrene insulation board mainly take polystyrene as raw materials, polystyrene itself is an exnt low thermal conductivity materials, and extruded and molded to form a tight honeycomb structure, which can effectively prevent the heat conduction. Thermal conductivity of Polystyrene board is 0.028 / m k, has high thermal resistance, low pansion rate characteristics. Thermal conductivity is much lower than other insulation materials. At the same time, the board is light, inexpensive and has a stable chemical structure and sical structure, which can ensure lasting and stable insulation performance of the material, and it is one of exnt thermal insulation materials.
2, high-strength compressive properties
Polystyrene board have high compressive strength, it can remains unchanged for a long time even if it is soaked the in water , have great bearing capacity and good impact resistance.
3, superior water resistance, moisture resistance
Polystyrene board has a tight closed-structure, polystyrene molecular structure itself is not hydrolic, there is no gap both in the front and back of the plate so water absorption is very low, and moisture and impermeability is exnt.
4, weather resistance
Polystyrene board has exnt anti-corrosion, anti-aging, and the thermal insulation life is up to 30-40 years.
5, light weight, construction convenience
The completely closed-foam structure of Polystyrene board cab form a lightweight and uniform honeycomb structure ,so it has high hardness, and not easily damaged, easy to handle, easy to install, easy to cut, and it will not affect the bearing capacity of the structure when used as a roof insulation.
