In dependence on the type and later application, the layers of cables are made from many different kinds of polymers. However, most often, because of good mechanical properties and many other advantages, they are first of all made from polyvinyl chlorine (PVC). The aim of the conducted research was to discover the influence of modifying PVC with selected agents that is a blowing agent, in the course of the extrusion process, inclusive of determination how the modification affects selected technological properties and properties of the surface of PVC extrusion product. The article presents specification of cellular extrusion process of thermoplastics. In the research, endothermic and exothermic chemical blowing agents in the amount of 1.5% by mass were used. The experiments involved measuring output, energy consumption and energy efficiency of the process.

Keywords: Extrusion, effectiveness, poly(vinyl chloride), chemical blowing agents
