APPLICATIONS
TPP is a non-flammable crystalline compound; melts at 49-50 C; soluble in benzene, chloroform, ether, and acetone. It hydrolyses rapidly in alkaline solutions at normal ambient temperature to give phosphoric acid, diphenyl phosphate and phenol, readily hydrolyses in strong acidic conditions at high temperature but slowly in acidic and neutral solutions. TPP is used as; · Flame-retardant in many plastics and reins especially in phenolic resin for the manufacture of electrical and automobile parts. · Component of hydraulic fluids and lubricant oils. · Non-flammable plasticizer or additive in cellulose for photographic films, polyester and polyurethane. · Non-combustible substitute for camphor in celluloid for fireproof. · Plasticizer in lacquers and varnishes, vinyl automotive upholstery and in cellulose acetate articles. · Impregnating agent for roofing paper

GENERAL DESCRIPTION OF FLAME RETARDANT AGENT
Flame Retardant are substances that can be chemically inserted into the polymer molecule or be physically blended in polymers after polymerization to suppress, reduce, delay or modify the propagation of a flame through a plastic materials. There are several classes of flame retardants; Halogenated Hydrocarbons (Chlorine and Bromine containing compounds and reactive flame retardants), Inorganic flame retardants ( Boron compounds, Antimony oxides, Aluminium Hydroxide, molybdenum compounds, zinc and magnesium oxides ), Phosphorous containing compounds (Organic phosphate esters, phosphates, halogenated phosphorus compounds and inorganic phosphorus containing salts).
