Selecting the right insulation is critical for cable longevity and performance. Our Wire Insulation Chart compares common compounds—PVC, XLPE, PTFE, FEP, and Tefzel®—across key properties: maximum operating temperature, dielectric breakdown voltage, abrasion resistance, and chemical/UV exposure limits. Use this chart to quickly identify which material meets your design’s environmental, electrical, and regulatory requirements.
