Electromagnetic processing of commingled plastics for recycling applications

Abstract

In order to evaluate an economical alternative for the recycling of commingled plastics, pellets of Polyethylene (PE) and Polyvinyl Chloride (PVC), two incompatible widely used polymers, were compression-molded using radio-frequency (RF) heating and conventional conductive heating (CH). The main advantage of the RF system over the CH system is the shorter processing time. However, the fast heating in the RF process caused PVC degradation and reduction of the mechanical properties of the molded products. To solve this problem Chlorinated Polyethylene (CPE) was placed, as a process-specific additive, at the interface between the PVC and PE, using a solvent coating technique.
