Destruction of polyvinyl chloride under extrusion
Abstract
An common industrial application of polyvinyl chloride (PVC) is the extrusive insulation of electric wires and cables. Experimental results are presented on the thermal and mechanical destruction of PVC under extrusion. Under extrusion conditions (at temperatures higher than 150 C), the evolution of hydrogen chloride determines practically the entire process of PVC destruction. The use of the present data to establish hygienic standards regarding safe concentrations of PVC destruction products in the work environment is discussed.
