Plastic has lower specific gravity and excellent processability than metal and inorganic materials but has a weak heat resistance and flame retardancy. Plastic not only increases human and material damage in emergencies such as fires but also becomes raw materials that cause fires. Due to these weaknesses, it is mandatory to use flame retardant plastics in combustible products worldwide, and in particular, a thin UL-94 V-0 flame retardant plastic is required depending on the trend of lightweight. In this study, pellets for each eco-friendly phosphorus-base flame retardants content were prepared through an extrusion process, and flame retardancy was evaluated with samples for each thickness (0.8 T, 1.2 T, 3.2 T) through a UL-94 V test. In addition, a study on flame retardancy was conducted along with the optimization of flame retardants content using the non-halogen-based flame retardant technics such as the intumescent system and the LDH technology. |
