High Performance Extruded Polystyrene Foam Board for Airport Runway

Nanjing Ourgreen 500Kpa,CO2 Styrofoam Sheet, Extruded Polystyrene Foam Board for Airport Runway


Nanjing Ourgreen 500 Kpa Extruded Polystyrene Foam Board in Airport Runway Parking Area


Frost - heave causes uneven ground on roads of Highspeed Railway, Pavement and Airport, which

was mainly invaded by Cold Weather, Moisture and Frost. Ourgreen XPS Board prevents penetration

of Moisture, decrease damage of extreme weather on road base, minimize freeze - thaw effect, and

prolong its life so as to ensure traffic safety.


Usually a High Compression Strength of 500Kpa to 700Kpa is applied in this special field.


Blowing Agents of Ourgreen 500Kpa Extruded Polystyrene Foam Board


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, which enables XPS to

bear higher Compression Strength.


The existence of CO2 presents higher System Pressure requirement to the extruder. Due to boiling point

of CO2 is as low as - 78.4 degree, the Extruding System Pressure must be kept around 25Mpa to maintain

its liquid state, which means Mould can not be opened largely. This also determines that thickness greater

than 50mm at 700Kpa is difficult to produce.
