(57) [Summary]nA halogen-free flame-retardant additive comprising a salt of an inorganic phosphorus-containing acid with a polymer compound, the polymer compound being a homopolymer or copolymer and formed from at least 10 repeating units, and a plurality of An additive comprising a linear skeleton containing a basic nitrogen functional group of. This additive is suitable for use in polymeric materials alone or in combination with other flame retardant additives to reduce soot emissions, reduce corrosive gas emissions and enhance flame retardant properties. Results in the specified additives. The flame retardant additives of the present invention are compatible with a variety of thermoplastic and thermosetting polymers useful for wire and cable insulation, heat recoverable items, electrical tapes and molded parts. This additive may be incorporated as a dispersant in a coating composition optionally comprising additional ingredients such as other flame retardants, fillers, colorants and the like. In addition, this additive can be incorporated into coke, mastic and seal materials. |
