ABSTRACT:
A composition based upon a blend of lower alkyl or lower alkoxyalkyl polyacrylate ester elastomers with one or more materials selected from liquid butadiene acrylonitrile copolymers and halogenated fire-retardant plasticizers. Blends with the liquid butadiene acrylonitrile copolymers include from about 5 to about 50% by weight of the copolymer and from about 50 to about 95% by weight of the polyacrylate ester elastomer. Blends with the halogenated fire-retardant plasticizer include from about 5 to about 100 parts by weight of the halogenated fire-retardant plasticizer per 100 parts of the polyacrylate ester elastomer. Hydrocarbon-resistant sealant compositions further contain effective amounts of one or more plasticizers in amounts effective to plasticize the blend together with one or more reinforcing materials. Flame-resistant sealant compositions utilize phosphate ester plasticizers and further contain one or more flame-retardant materials including alumina trihydrate, magnesium carbonate and magnesium hydroxide hydrate.
