- With perfect closed alveolate construction, XPS heat insulation plate is considered to be the best insulation material in the market. Granules from recycled EPS plate, as the main material, go through the die foaming extruder, calibrator, haul-off and cutting unit. With lower density,water absorption,thermal conductivity and vapour penetrability than of other kinds of heat insolution plates, XPS heat insulation plate features with high strength, low wight, airtightness, corrosion resistance, aging resistance and low cost.
- XPS heat insulation plate extrusion line has two types: single screw tandem extruders type and co-rotation parallel twin screw extruder with single screw extruder.The models are: 135/150 single screw tandem extruder type and 75/150 co-rotation parallel twin screw extruder with single screw extruder. Because of high mixing efficiency, co-rotation twin screw etruder can process material of different components.
