PVC Compound Type A-fr
About PVC Compound Type A-Fr Color Variant
PVC Compound Type A‑FR is a flame-retardant, thermoplastic insulation and sheathing material widely used in electrical cable manufacturing, conforming to IS 5831 Type A/D FR standards. This versatile compound is available in a range of color variants tailored to specific functional requirements. For insulation applications, colors such as Red, Yellow, Blue, Black, Green, Grey, and White are commonly used to facilitate phase identification and wiring clarity. In contrast, sheathing applications typically utilize more neutral or protective tones like Natural (NAT), White (WHT), Black (BLK), and Grey (GRY), providing durability and aesthetic conformity. Each color variant maintains consistent physical and electrical properties, ensuring safety, heat resistance, and flame retardancy across diverse electrical installations.
