The single screw extruder is an important component in extrusion of polyolefin production. The concept of long L/D and two stage unique design ensure high plasticization, low temperature plasticization. It has following features. -High throughtput rates -Low melt temperatures - Good melt homogeneity -Wide range of processing applications Unique straight or spiral grooved feed bush with force cooling system and unique screw ensure high plastification rates to be achieved
