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. Therefore this plate can be widely used in house insulation system,in cold storage、camps、barns and civil constructions, in ground constructions of airport raceway and square, in road and railway engineering constructions,in heat insulation system of apartments,officebuildings and workshops.
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 etrudercan process material of different components.Newly forming machine designed by Jwell, adapting CO2 as forming agent, which is for taking palce of freon and butane , features of green environment protection and low cost consumption.
