Problems solved by technology

However, the oxygen index of ordinary TPU is only 17.0% to 18.0%, which is a flammable material, and the char formation rate is low when burning, and it has a strong droplet phenomenon, which limits its application range; in order to enhance the flame retardancy of TPU, the current general The method is to add a halogen-containing flame retardant to it, but the chlorine-containing flame retardant mainly achieves the flame-retardant effect through the gas-phase flame-retardant mechanism, and will release a large amount of toxic and harmful gases when burning, which not only pollutes the environment, but also seriously affects the life safety of the parties; In this context, chlorine-containing flame retardants have been banned by many countries
