Polymer solid state heat treatment process
In order to obtain higher-quality products after extrusion and granulation of melt polymers, it is necessary to control key parameters such as moisture content, VOCs content, and crystallinity. Drying and tempering by a heat treatment process in the solid state can well achieve this goal.
