Thickness Requirement of Extruded Polystyrene Foam Sheets
When XPS is installed for building insulation, as being used together with Roof / Wall / Floor, a thickness
of less than 50mm is enough.
In area such as Cold Chain Logistic Truck manufacturing, Cold Storage, Insulation
board at thickness of 75mm / 100mm or more is preferred. Especially in Cold Storage, where release of
cold is critical. People tend to require large panel like 2440X1220X100mm or even 2440X1220X150mm.
In this case XPS Extrusion Line with small capacity is far from enough. Bigger Extruder with higher capacity
of 800 to1500 Kg/h is expected.

Phase out of Freon as Blowing Agent in Ourgreen Extruded Polystyrene Foam Sheets Production:
XPS Foam Board, at its early stage, is produced with Blowing Agents of HCFC, a kind of Freon. Freon
technology is easily accessible for many manufacturers. However, as Freon damages Ozone Layer, it
is generally recognized that Freon must be phased out world wide, which is plan of UNIDO.
Ourgreen applies CO2 as well as other non freon gases in XPS production, making final XPS Foam
Board totally eco friendly. We are contributing to environment protection by replacing Freon.
Together we build our green world!
