Abstract
Embodiments of a flame retardant compound are provided. The flame retardant compound includes a polymer base resin and a flame retardant additive distributed within the polymer base resin. The flame retardant additive includes inclusion complexes that are made of at least one guest molecule and at least one carbonific host molecule. The at least one guest molecules is a polyoxometalate ionic liquid. The flame retardant compound achieves a limiting oxygen index of at least 25% according to ISO 4589. Additionally, embodiments of a flame retardant cable are provided that utilize the flame retardant compound as a jacketing material.
