Flame-retardant science and technology is a science developed to meet the needs of social safety production and life, prevent fires, and protect people's lives and property. Flame retardant is the application of flame retardant technology in real life. It is a special chemical additive used to improve the combustion performance of combustible and combustible materials. It is widely used in the flame retardant processing of various decoration materials. The material processed by the flame retardant can effectively prevent, delay or terminate the propagation of the flame when attacked by external fire sources, thereby achieving the flame retarding effect.
