Abstract
An improved fire retardant polystyrenic composition comprising a polystyrenic resin, a fire retardant agent selected from the group consisting of halogenated and phosphorous-containing fire retardant agents and combinations thereof, antimony oxide and an aliphatic nitrogen-containing compound selected from the group consisting of amines, amides and ammonium compounds containing from 8 to 25 carbon atoms, mixtures thereof and the oxyalcoylated derivatives thereof.
Claims21
A self-extinguishing polystyrenic composition, comprising:
- a. a polystyrenic polymer;
- b. a fire retardant amount of a halogenated organic fire-retardant agent selected from the group consisting of polyhalogenated biphenyls, polyhalogenated biphenylethers, perhalopentacyclododecane, and tris (2,3-dibromopropyl)phosphate;
- and
- c. an antistatic agent selected from the group consisting of lauric diethanolamide, ethoxylated cetylamine, pelargonic acid triisopropanolamide, lauric monoisopropanol amide, N-(3-dodecyloxy-2-hydroxypropyl)ethanolamine, and (3-laurylamidopropyl)-trimethylammonium methyl sulfate in an amount sufficient to enhance the self-extinguishing properties of said composition.
