Performance and Purpose
This product is colorless to pale yellow oily liquid, soluble in benzene, alcohol, ester and carbon tetrachloride. At 20℃, its aquatic solubility is 1.6g/L. This product is insoluble in aliphatic hydrocarbons. Chlorine content is 32.5%, and phosphorus content is 9.5%. As the molecule contains both phosphorus and chlorine, its flame-retardant properties are very significant; at the same time, the product is plasticized, moisture-proof, anti-static and so on. Therefore, it is an additional flame retardant. This product is suitable for flame retardancy of polyurethane, PVC, polystyrene, phenolic resin, acrylic resin, rubber and coating. It is generally used with antimony oxide to increase the flame-retardant efficiency of antimony oxide. The amount is about 10%
