The Full name is Expanded Polystyrene board, also known as foam board or EPS board. EPS insulation board is new green energy-saving foam board which mix polystyrene resin with polymer, and add catalyst at same time, and then extruded out to a continuous closed-cell ,rigid, New, environmental protecting, and energy saving foam. Its internal is a separate closed Bubble structure, it is a thermal insulation material with low thermal conductivity, high compressive strength, low water absorption, moisture resistance, airtight, light weight, corrosion resistance, anti-aging and other excellent performance. It is a new insulation materials which is widely used in construction industry,

Features:
1, Excellent thermal insulation performance
Polystyrene insulation board mainly take polystyrene as raw materials, polystyrene itself is an excellent 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 linear expansion 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 physical structure, which can ensure lasting and stable insulation performance of the material, and it is one of excellent 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-cell structure, polystyrene molecular structure itself is not hydrophilic, there is no gap both in the front and back of the plate so water absorption is very low, and moisture and impermeability is excellent.
4, weather resistance
Polystyrene board has excellent anti-corrosion, anti-aging, and the thermal insulation life is up to 30-40 years.
5, light weight, construction convenience
The completely closed-cell 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.
