Microencapsulated red phosphorus( MRP) was prepared through inverse suspension poly-merization of melamine and formaldehyde ( MF) on the surface of red phosphorus ( RP) powder, and its structure was characterized by Fourier transform infrared ( FT-IR) spectroscopy, scanning electron mi-croscopy (SEM), and X-ray photoelectron spectroscopy (XPS).The limiting oxygen index (LOI) for MRP composites with polypropylene ( PP) or polyamide 6 ( PA6) was measured.The thermal property of microencapsulated red phosphorus ( MRP) was evaluated and the fire retardant efficiency was tested in PP and PA6 matrix.Experimental results from IR, SEM and XPS confirmed the coating of MF resin onto the surface of RP powder.In the flame retardancy of PA6 and PP, the experimental results showed that the flame retarded PA6 had the LOI>28 .2%when the loading of microencapsulated red phosphorus was 15 wt%, and the flame retarded PP had the LOI >22 .4% when the loading of microencapsulated red phosphorus was 15wt%.
