A flame-retardant polymer composition comprising mineral blends melt mixed into a polymer matrix is described. The mineral blend comprises alkaline earth carbonate, kaolin, and magnesium hydroxide. The polymer matrix may include ethylene vinyl acetate and polyethylene, and may also contain dicarbonamide peroxide. The flame retardant polymer composition shows a UL94 flammability rating of V-0 or V-1, and does not contain halogens or aluminum hydroxide. The flame retardant polymer composition can be suitable as a wire coating or used for passive fire resistance in vehicles and buildings.
