Abstract

Extruded thermoplastic synthetic resin is cooled directly to maintain the plasticising and kneading temp. within the desired ranges by injecting water or liquid nitrogen directly into the extrudate during extrusion and distributing the predetermined quantity of injected water or nitrogen uniformly throughout the extrudate which is also subjected to degassing.
