Foam machine

Plastic foam extrusion machine, the raw material is putting into the extruder, after heating, mixing and plasticizing, foam agent will be injected into machine body under high pressure and sufficiently mixing uniformity by screw. After that, the melt material will go through the mold and instant release pressure, after cooling, sizing, draw-off and cut; it becomes a different type of plastic foam products. An extrusion polystyrene foam for heat insulation (XPS for short), has a perfect closed-pore alveolate structure. Its density, water absorption, coefficient of heat conducting and the coefficient of steam pervasion are all lower than those of other board heat insulation and preservation materials and they have the characteristics of strong intensity, light material, airtight, anticorrosion, aging resistance, low cost, etc.
