In this study, tensile properties such as tensile strength and tensile strain of single core PVC-based cable formulation with higher K values were statistically optimized with design of experiments method (DOE). This DOE method was established with the K-80 and K-90 values of PVC and other additives. Formulation inputs were determined as the K value of PVC, plasticizer, stabilizer and TPU according to literature review, theoretical information, material, and process requirements. Other formulation inputs of ESBO, calcined kaolin and PVC, were held constant at 4, 15 and 100 phr, respectively. Production trials were carried out by extrusion process according to the experimental design matrix obtained with the DEO method used in the Minitab Software. Tensile tests of prepared cable samples were performed to determine the tensile strength and tensile strain of single core PVC cable samples. Tensile test results were analyzed using factorial design and analysis of variance (ANOVA). According to the statistical results, linear regression models had better fit between experimental and prediction results. It is worthy to note that plasticizer was found to be the most significant factor for both tensile strength and tensile strain of PVC cable insulation with higher K values. It was also concluded that optimizing the K value of PVC contributes to both the processability and the improved tensile properties. Graphical abstract: [Figure not available: see fulltext.].
