Development and Testing of Waste poly(Vinyl Chloride) Based Solvent Cement for Bonding of poly(Vinyl Chloride) Pipes and Fitting

Abstract

Recyclates of waste poly(vinyl chloride) (wPVC) fill materials were used to produce solvent cement. Recyclates of wPVC were made by mechanical recycling of wPVC sheets from power plant cooling tower fill materials. Recyclates of wPVC were analyzed and used to develop solvent cement for bonding of PVC pipes and other molded objects. The formulation of wPVC based solvent cement was optimized. Virgin PVC based solvent cement was also made by applying the same optimized conditions to compare it with wPVC based solvent cement. The newly developed solvent cements were analyzed and applied to PVC pipes to find out their bonding strength compared with the bonding strength of commercial solvent cement. There were no significant differences in the results of these three different solvent cements. So recycling of wPVC into solvent cement is suitable for PVC pipes bonding applications and it has a great potential to achieve benefits for the economic and environmental conditions.
