    Blowing Agents of Ourgreen X700 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.
