Abstract: The present disclosure provides a flexible, halogen-free, flame retardant composition. The composition includes from about 25 wt % to about 95 wt % of a thermoplastic polyurethane (TPU); from about 5 wt % to about 50 wt % of an olefin block copolymer (OBC); and from about 30 wt % to about 70 wt % of a flame retardant. The flame retardant is selected from resorcinol bis(diphenyl 5 phosphate) (RDP), bis diphenyl phosphate (BDP), bisphenol-A bis(diphenyl phosphate) (BPADP), aluminum trihydrate (ATH), a nitrogen/phosphorus-based halogen-free flame retardant, epoxidized novolac resin, and combinations thereof. The composition requires no compatibilizer for the TPU and OBC. The composition finds application in wire and cable structures.
