ABSTRACT:
Salts of phosphonous acids are useful as flame retardants in plastics. Preferred salts are calcium or aluminum salts of phenylphosphonous acid and of methanephosphonous acid. Plastic molding materials rendered flame-retardant in this way are useful for manufacturing molded parts, especially electrical components, mechanical components, plugs, mounts, housings, coverings, sheathings and overcoatings.
