ABSTRACT:
A liquid-like dispersion, pourable at room temperature, for use as a flame retardant for polymers, is provided. The dispersion has relatively low viscosity, is pumpable and dust-free and, when introduced during processing of thermoplastics, paints, rubber, thermoplastic elastomers and the like, provides flame retardancy to the finished product. The dispersion comprises a flame retardant solid powder dispersed in a liquid carrier, the dispersion containing 1 to 3 weight percent of a hyperdispersant. Preferably the solid powder is antimony oxide or a mixture of antimony oxide and another particulate solid such as an aromatic halogenated flame retardant powder or a powdered lead stabilizer.
