摘要:
Halogen-free TPU compositions comprise in weight percent based on the weight of the composition: A. 1 to 99% thermoplastic polyurethane (TPU), B. 1 to 50% tris(2-butoxyethyl)phosphate (TBEP), C. 1 to 70% metal hydrate, and D. 1 to 70% organic phosphate ester other than tris(2-butoxyethyl)phosphate. These compositions exhibit better smoke suppression as compared with conventional organic phosphate flame retardant TPU compositions such as those based on resorcinol bis(diphenyl phosphate) (RDP) and bisphenol-A bis(diphenyl phosphate) (BPADP) in the absence of TBEP.
摘要:
Halogen-free, flame-retardant thermoplastic compositions that include a styrenic block copolymer, a low-melting, phosphorus-based flame retardant having a melting temperature no higher than 170° C, and a blend of solid intumescent phosphorus and nitrogen-containing flame retardants. The blend of solid intumescent flame retardants include at least two phosphorous and nitrogen-containing phosphoric acid salts that synergistically enhance the flame-retardant properties of the compositions relative to compositions that include other flame-retardant packages.
