Abstract
This inventon relates to flame-retarded cross-linked elastomer compositions obtained from an elastomeric polyurethane prepolymer; an organic fire-retardant additive containing chlorine and/or bromine; a compound of antimony; and a hexaalkoxymethyl melamine. These new compositions are self-extinguishing as well as non-dripping.
