Abstract: Formulations comprising from 10 to 80% by weight of the formulation of a halogenated epoxy resin; from 1 to 15% by weight of the formulation of an antimony based fire retardant; from 1 to 10% by weight of the formulation of an inorganic or non-polymeric organic phosphorous containing fire retardant; and from 1 to 30% by weight of the formulation of a curative system are provided. The formulations are particularly suitable for producing aircraft interior composite components having good fire retarding properties, low smoke emission, low smoke toxicity and low heat release properties. The formulations also have excellent processing and mechanical properties. Further components may be included in the compositions to improve various properties, including the fire retarding, low smoke emission, low smoke toxicity and low heat release properties and to also further improve the processing and mechanical properties, including toughness. Compositions produced from the formulations have excellent processing and mechanical properties, and may also have good surface finishes.
