Abstract:
A low smoke, zero halogen (LSZH) polymer composition is provided. The LSZH polymer composition includes a polymer resin, and a flame retardant package dispersed within the polymer resin. Less than 25% by weight of the polymer composition is the flame retardant package. The flame retardant package includes an acid source, a carbon source, and an LSZH additive. The LSZH additive includes a polyoxometalate ionic liquid and a synergist carrier. The LSZH polymer composition has a limiting oxygen index of greater than 31%. The LSZH polymer compound is suitable for use in electrical or tele-communication cables.
