One of the perspective methods of polymer processing - co-extrusion of combined materials in complex shift conditions - attracts interest. Sinuation of an extrudate is achieved by twisting of separate flows and by the difference of thermal expansion coefficient of each polymer, that leads to twisting of monofiberduring its cooling and coagulation after the molding channel. Coiled combined polymeric products being obtained by co-extrusion with twisting of combined layer-sector flow process, ensure more impervious connecting seams, high mechanical tensile strength, reduce swelling, increase the molding channel capacity, that in whole increases the quality of thermoplastic products.
