PVC Compound Type A, widely used in electrical applications, is formulated to meet specific performance and safety standards, with color variants serving both functional and identification purposes. Each color—such as black, red, blue, yellow, green, and white—not only signifies its role in electrical wiring (e.g., black for insulation, green for grounding, red for live wiring) but may also slightly differ in formulation to accommodate pigment effects on thermal stability, UV resistance, and flexibility. For example, black compounds often include enhanced UV stabilizers for outdoor use, while green compounds used for grounding may incorporate specific additives for high visibility and durability. Despite color differences, all variants maintain key electrical properties such as high volume resistivity, flame retardancy, and mechanical strength, ensuring reliable performance in cable insulation and sheathing across industrial and domestic environments.
