In this paper, red phosphorous (RP) was coated by aluminum hydroxide to prepare modified RP (MRP). MPR was blended with high density polyethylene (HDPE) to obtain MRP/HDPE composites. And the properties of MRP/HDPE composites were investigated. The effects of MRP on the flame retardancy, thermal decomposition behavior and mechanical properties of HDPE were also discussed.

Flame retardant properties of ammonium polyphosphate (APP) and its two kinds of microcapsules, MFAPP with a shell of MF resin and EPAPP with a shell of epoxy resin, were studied in styrene-butadiene-styrene rubber (SBS). The results indicate that the microencapsulation of APP leads to an increase in LOI in SBS compared with APP. When dipentaerythritol is incorporated into the SBS composites containing APP microcapsules, a further improvement in flame retardancy of the composites is observed. Moreover, thermal decomposition behavior and mechanical properties of the SBS composites are investigated.

Flame retardant and mechanical properties of ethylene-vinyl acetate copolymer (EVA) composites containing ammonium polyphosphate (APP) and its microcapsules, MFAPP with a shell of melamine–formaldehyde resin and EPAPP with a shell of epoxy resin, were evaluated in EVA. The results indicate that APP after the microencapsulation leads to an increase in LOI in EVA compared with APP. When dipentaerythritol is added into the EVA composites containing APP microcapsules, a further improvement in flame retardancy of the composite is observed. Moreover, thermal decomposition behavior and mechanical properties of the EVA composites are investigated.

Abstract In this study, two different surface-modified silica nanoparticles, amino-functionalized nanosilica (ATS) and methyl-functionalized nanosilica (HDS), were separately used as nanofillers to fabricate PA66-based nanocomposites by melt blending. The morphology and interface characteristics of the two nanofillers in the composite system and their influence on the mechanical properties, thermal decomposition behavior, and crystallization behavior of PA66 were investigated. The Avrami and Mo methods were applied to study the non-isothermal crystallization kinetics of the nanocomposites. The results revealed that different surface modifications of silica nanoparticles can produce different influences on the mechanical properties and thermal decomposition behavior of the final nanocomposites. The addition of ATS helps increase the strength and stiffness of PA66/ATS nanocomposites, and in the meantime enhances the thermal stability of PA66. The case of HDS is opposite to that of ATS; however, its incorporation can improve the toughness of the material. In addition, the results also indicate that ATS possesses strong heterogeneous nucleation capability, the introduction of which can accelerate the crystallization rate and increase the crystallization temperature, as well as the degree of crystallinity of PA66, while HDS displays an obvious blocking effect on the crystallization process of PA66.
