Jacket fire-retardant materials for plenum cables are typically made of which materials?

Explanation:
Plenum spaces require jacket materials that minimize smoke and toxic gases while withstanding higher temperatures. Teflon (PTFE) and high‑temperature PVC fit that need well, offering superior flame resistance and much lower smoke production than standard jackets. Regular PVC, polyethylene, or nylon don’t meet the stricter plenum requirements, so they’re not typical for plenum-rated cables. That’s why jackets made of Teflon or high‑temperature PVC are the common choice.
