How to determine whether the flame retardant bristles of a brush meet safety standards?

With the rapid development of China's rail transit, the demand for flame-retardant brushes for escalators and elevators is constantly increasing. Making flame-retardant brushes requires the use of a safe, environmentally friendly and reliable flame-retardant bristle material for processing. Where is the production of flame-retardant bristles? Many of the flame retardant bristles on the market are of poor quality, and the flame retardant additives contain halogen elements. After combustion, toxic and harmful gases are produced, and the flame retardant effect is not up to standard. We need to find flame retardant bristles that meet safety standards.
Flame retardant wool is a material with flame retardant properties, which can effectively reduce the occurrence and spread of fires, and protect people's lives and property safety. In order to ensure the safety performance of flame retardant fibers, a series of safety standards have been formulated, including material selection standards, production process standards, combustion performance standards, toxicity standards, thermal stability standards, and safety standard certification. The combustion performance of flame-retardant fibers is an important indicator for evaluating their safety performance. Flame retardant filaments that meet safety standards should have good flame retardant performance, which can effectively suppress the spread of fire and reduce the generation of smoke and toxic gases in the event of a fire. The combustion performance standards include combustion speed, toxicity of combustion products, and other indicators.
There are two types of flame retardant bristles produced by Mingwang: nylon and PP, which are made of pure and environmentally friendly raw materials mixed with imported flame retardant materials. They are halogen-free and flame retardant, safe and environmentally friendly. They have passed the EU UL94V-0 safety test, and can be extinguished immediately after ignition. The combustion time after ignition is less than 10 seconds, and droplets will not ignite the degreased cotton. When extinguished, they produce white smoke with no irritating odor. They have been successfully applied in elevators of Hong Kong and Guangzhou subways, and are long-term partners of CRRC.
