Extrusion Equipment for Reactive Blending

The major equipment for manufacturing various kinds of polymer alloys is a screw extruder. Screw extruders are practically classified into single and twin screw types. A single screw extruder is used mainly for diversified thermoplastics processing, for example in blow molding, film and pipe extrusion, and injection molding. On the other hand, a twin screw extruder is generally used for blending and controlling the microstructure of a polymer alloy, and polymerization such as grafting [1-4]. Further, a reciprocating single screw extruder can be classified into the same categories as a twin screw extruder from the point of the mutual interaction between screw flight and barrel.
