Abstract The polymer blends with the flame retardancy such as PPE are attracting lots of attention in various fields such as construction materials, automotive interiors, electric and electronic devices etc. In the present study, poly(2,6-dimethyl-1,4-phenylene ether) (PPE)/nylon 66 blends at the ratio of 60/40 were prepared by twin screw extruder at 275 oC. with the compatibilizer and an impact modifier, respectively. Non halogenated flame retardant was used to endow the flame retardancy and well-dispersed flame retardant particles without large agglomerate in the PPE/nylon 66 blends were confirmed through the EDX spectroscopy. For the testing of flame retardancy, UL94V method was carried out and the cone calorimetry was used. The mechanical properties of PPE/nylon 66 blends optimized by each component were deteriorated with increasing the flame retardant loadings. At the result of flame retardany test, HRR (heat release rate) was dropped as well as the maximum peak of the blends were reduced and broadened with increasing FR loadings. In addition, the blends containing ~3 phr flame retardants represented the no grade, while further addition showed V0 grade apparently.
