Research progress of flame retardant modified polycarbonate/acrylonitrile butadiene styrene alloys: a review

This paper focuses on the current status and significance of research on flame-retardant modified polycarbonate/acrylonitrile butadiene styrene alloys (PC/ABS). PC/ABS alloys, as a kind of widely used modified engineering plastics, have many advantages, but their poor flame-retardant properties limit the applications. Flame retardants can give flammable polymers flame retardant properties and reduce the risk of fire, thereby mitigating potential environmental damage from uncontrolled burning and toxic fume release. This review focuses on the current research status of additive flame retardants, which are the most widely used in the current market, mainly including phosphorus-based, silicone-based and synergistic flame retardants. This review finds that in the future, flame retardant PC/ABS will develop in the direction of increasing market demand, improving environmental protection requirements ( e.g. , seeking halogen-free alternatives and enhancing material recyclability), and relying on technological innovations such as nanomaterials and renewable additives to optimize flame retardancy and overall performance. These advancements contribute significantly to developing safer and more environmentally sustainable materials.
