Effect of Dioctyl Phthalate Plasticizer Loading on Physico-Mechanical Properties of Several Polyvinyl Chloride Systems
Year: 2017
Type: article
Abstract: Blends were prepared of three grades of polyvinyl chloride (PVC) as a base polymer, with three different stabilizer systems; all were mixed with variable compositions dioctyl phthalate (DOP) as plasticizer. Physical and mechanical properties were measured for the blends. Results showed that as the plasticizers’ concentration increased, the tensile strength, hardness and specific gravity of PVC compound decreased while elongation at break increased. There were slight noticeable effects while using different stabilizers systems. The grade of PVC has an influence that coincides with the polymer molecular weight. Furthermore, it was concluded that adding up to 10 phr of plasticizer didn’t have any negative effect on final physical and mechanical properties of the products.
