The cable insulation and sheathing industry uses many different types of plastics depending on usage, application. Physical and electrical properties are one of the most important factors that compete and help to choose these materials when compared with other materials. These properties change with the change of the chemical components of the plastics mixture. The use of PVC material in the manufacture of cable wire coating has been used for decades. In this study, the effect of changing the proportions of the used components in the PVC mixture of the physical and electrical properties of cable wiring materials was investigated. Emphasis was placed on three properties: Tensile Strength and Loss of Mass and Insulation Resistance. In this study author discussed how to enhance these properties and improve them by working to raise the proportions of some of the substances in the PVC mixture while preserving other properties. The study aimed to prove the strong relationship between some components of PVC mixture used in cable insulation and sheathing industry and the physical and electrical properties of these products, and then focus on three components in the mixture and three properties. Random samples were taken and the mean percentages of the ingredients in the mixes were taken using various tools and several statistical methods such as correlation coefficient and regression analysis to prove the relationship between the ratios of some materials and the properties. After the analysis, the p-value was less than 0.05, which reinforces the relationship between the ratio and the properties. Finally, the physical and electrical properties of PVC blends can be improved by changing component ratios to reach the optimized mixture for specific use and application, taking into account other competitive issues such as the final price of the product, environmental impact, and others issues.
