The contents of the reaction vessel are pressurized and constantly combined to maintain the suspension and make sure a uniform particle dimensions in the PVC resin. The response is exothermic and so necessitates cooling. As the volume is minimized throughout the response (PVC is denser than VCM), water is continuously additional to your mixture to keep up the suspension.[9]
Have you at any time puzzled how PVC plastic is designed? It is really a fascinating course of action that entails many steps. Let us examine the production journey of the functional material.
