Abstract:
Poly(hexamethylene adipamide), (also referred to as Nylon 6,6) compounds that are flame retardant using non-halogenated ingredients are disclosed. Polyphenylene ether or bismaleimides act as synergists when used in specific amounts in combination with polyphosphonate to achieve a V-1 or V-0 rating in a UL 94 test at thicknesses of about 3.18 mm.
Abstract:
Poly(hexano-6-lactam) (also known as Nylon 6) compounds that are flame retardant using non-halogenated ingredients are disclosed. Polyphenylene ether acts as a synergist when used in specific amounts in combination with polyphosphonate to achieve a V-0 rating in a UL 94 test at thicknesses of about 3.18 mm.
Abstract:
High temperature nylon compounds that are flame retardant using non-halogenated ingredients are disclosed. Poly phenylene ether, or alternatively the combination of polyphenylene ether and bismaleimides, act as synergists with polyphosphonate to achieve a V-0 rating in a UL 94 test at thicknesses of about 3.18 mm or, preferably, about 1.59 mm.
Abstract:
A completely non-halogenated flame retardant polycarbonate compound is disclosed. The compound comprises a polycarbonate, non-halogenated drip suppressant ingredients which react in the presence of heat to form a drip suppressant adduct, and a non-halogenated char former. The compound can achieve a UL 94 rating of V-0 at a thickness of at least 3.2 mm and otherwise achieves no dripping/igniting of the cotton indicator during that test.
Abstract:
A non-halogenated flame retardant polycarbonate compound is disclosed. The compound comprises a polycarbonate, a non-halogenated, non-migrating, non-plasticizing flame retardant adduct. The compound can achieve a UL 94 rating of V-0 at a thickness of at least 3.2 mm and otherwise achieves no dripping/igniting of the cotton indicator during that test. The adduct is formed from an allyl-functional phenoxyphosphazene and a hydride-functional polysiloxane.
