Using a high-efficiency flame retardant system and by means of multiple-ingredient compatibilizing, PC/ABS alloys with excellent impact strength and flame retardant property were prepared. The experimental results showed that by using PS-g-MAH and SMA as synergistic compatibilizers, the notched Izod impact strength and flammability of PC/ABS alloy obtained in the present work can be up to 175 J/m and UL-94 VO, respectively.展开更多

The halogen free flame retardant was incorporated into PC/ABS to improve its flame retardancy. The flame-retardant properties of the PC/ABS/DPA-SiN blends were estimated by limiting oxygen index (LOI) values and CONE Calorimeter, while thermal stabilities were investi- gated through thermo gvavimetric analysis (TGA). The PC/ABS/DPA-SiN blends were thermally degraded at 400℃ for different amounts of time and studied by Fourier transform infrared spectroscopy (FTIR) to better understand the degradation behavior of PC/ABS/DPA-SiN.展开更多
