Abstract

By separating plasticizer using alkali solution at low temperature, the recycling of PVC and plasticizer is possible. A low temperature leaching process has been developed and the performance of the process investigated. An experimental study using various concentrations of NaOH solutions at different temperatures and processing time shows that treatment with 5 M NaOH solution at 100 °C gives a selective separation of the plasticizer without dechlorination of PVC. Surface changes of the treated PVC have also been examined.
