General Compounding Techniques Via Co-rotating and Counterrotating Twin Screw Extruders of Polymer Compounds for Wire Coatings

$15.00

Twin screw co-rotating and counterrotating twin screw compounding extruders are both used to compound multi-component polymers into a homogeneous product. This paper will present an overview of the various process tasks to achieve an acceptable product, including: material (s) feeding, screw design geometry, and downstream pelletizing systems. One-step operations that involve combining the compounding and cross head wire coating processes will also be addressed.
