PVC Compound ST-1 is a high-performance, thermoplastic insulation material widely used in the electrical and cable industry for low-voltage applications. Engineered to meet IS 5831 specifications for Type ST-1 compounds, it offers excellent electrical insulation, mechanical strength, and thermal stability. The compound is formulated in a range of color variants—including Black, Red, Yellow, Blue, Green, and White—to suit various functional and identification needs in electrical wiring systems. Each color serves a specific purpose: Black is preferred for cable sheathing due to its UV resistance, while Red, Yellow, and Blue are commonly used for phase identification. Green is reserved for earthing applications, ensuring safety compliance, and White is often used in signal or communication cables. These color-specific formulations maintain consistent properties such as high volume resistivity, reliable thermal performance, and compatibility with standard cable processing techniques.
