Mixing and Extrusion Technology for Polymer Blends and Alloys
Introduction
The development of blending technology has proven to be an extremely interesting and relatively low cost method to obtain tailored polymer blends and alloys with more flexible properties than existing polymer. Mixing is precursive to successful polymer blend formation and compatiblization. The single screw extenders and other continuous mixers are mainly used for compounding. The structural and morphological features of polymer blends and alloys are the result of complex interaction between the physical properties of the components and the mixing process. The morphology developed in the blend has a major influence on the mechanical properties. In order to provide reliable quantitative measures for predicting the morphology of the blends and alloys and to optimize processing conditions following study has been carried out: Extruder screw design for mixing improvement Determination of mixing performance in an extruder by using the designed experimentation technique
