Foam Extruders

XPS insulating materials are available in rigid boards in a wide range of sizes, thickness and compressive strengths that are ideally suited to a variety of construction applications.

This continuous extrusion process produces a consistent quality foam product with a closed-cell structure that looks like a mass of uniform bubbles with common walls between them. Close inspection reveals there are few, if any, voids between the cells and that a continuous smooth skin, top and bottom, has formed.

Then, a blowing agent either HFC,HCFC or a mixture of CO₂ is injected, which is for foaming the material. The material is then feed into the secondary extruder, which is for cooling from (Primary Extruder at 220 deg C) to +/- 90 deg C.  Under carefully controlled heat and pressure conditions, the mixture is forced through a die, at which time forming and the shaping of Boards occurs. Thereafter rigid foam board is then trimmed to the final product dimensions.

XPS insulation boards begin as a solid granule form (General Purpose Polystyrene - GPPS). The granules are fed into a primary extruder where they are melted at 220 deg C and small percentages of additives (Talc Powder, Calcium, Flame retardant and colouring pigment) are mixed with the viscous fluid that is formed in the Primary extruder.

Extruded Polystyrene (XPS) foam maintains its excellent insulating power over time, resists moisture absorption and has compressive strength that, when compared to other insulation products, is second-to-none.
