- thermoplastic resins Since ordinary thermoplastic resins have high flammability, in applications where flame retardancy is required, it is common to add flame retardants represented by halogen and phosphorus compounds to make them flame retardant. It is. However, such a flame retardant is not preferable in terms of environmental problems because it generates a more harmful gas than a thermoplastic resin during combustion. Further, such a flame retardant has a problem that the mechanical properties, electrical properties, heat resistance, weather resistance, and other physical properties of the thermoplastic resin are reduced in accordance with the added amount.
