Nanjing Ourgreen High Compression, 700Kpa, CO2 Extruded Styrofoam Sheets for Highspeed Railway Base
Nanjing Ourgreen High Compression, 700Kpa, CO2 Extruded Styrofoam Sheets Description
Ourgreen High Compression, 700Kpa, CO2 Extruded Styrofoam Sheet is a thermal insulation board of
extruded polystyrene, bearing a Compression Strength of 700Kpa, having a smooth surface to prevent
the formation of thermal bridges.
Due to its Extra High Compression Strength and good Thermal Resistance, it is widely applied in China
High Speed Railway Base . The XPS layer in such use prevent railway from damages caused by freeze
thaw.
Blowing Agents of Nanjing Ourgreen High Compression, 700Kpa, CO2 Extruded Styrofoam Sheet
The Blowing Agent of CO2 is added in the formulation in order to reach a Compression Strength of 700Kpa.
The CO2 tends to make smaller pore size and make density as high as 50Kg/m3 or above, which enables XPS to bear higher Compression Strength.
