摘要： A thermoplastic resin composition with improved flame retardance, flow and heat deflection temperature includes a thermoplastic resin; resorcinol diphenyl phosphate; and an additive blend. The additive blend includes a combination of melamine polyphosphate and ferrocene. The thermoplastic composition reduces the amounts of resorcinol diphenyl phosphate required for effective flame retardancy. Moreover, the effective amounts of melamine polyphosphate and ferrocene do not deleteriously affect other properties of the thermoplastic composition such as Izod strength, flow properties, and heat deflection temperatures. A process for manufacturing a thermoplastic composition is also disclosed.

摘要： A flame retardant thermoplastic resin composition comprises a thermoplastic resin comprising a polyphenylene ether resin, a high impact polystyrene resin or an acrylontrile-butadiene-styrene resin; an organo phosphate compound in an amount less than or equal to about 20 parts by weight for every 100 parts by weight of the thermoplastic resin; and a polyhydric alcohol compound in an amount of about 0.5 to about 5.0 parts for every 100 parts by weight of the thermoplastic resin. A method for the manufacture of the thermoplastic resin composition is also disclosed. The thermoplastic resin composition exhibits high flow characteristics and improved impact strength while providing effective flame retardance.
