The flame retardant performance of EPS Particles is one of its important properties that has attracted attention in many application fields.
Generally speaking, the flame retardant properties of pure EPS Particles themselves are relatively weak. It is a flammable material that burns easily when exposed to open flames and burns quickly, producing a large amount of black smoke and toxic gases. However, the flame retardant properties of EPS Particles can be significantly improved by adding flame retardants.
Currently, there are a variety of flame retardants available on the market for flame retardant treatment of EPS Particles. Common flame retardants include halogen flame retardants, phosphorus flame retardants, inorganic flame retardants, etc. These flame retardants achieve flame retardant effects through different mechanisms of action.
Halogen flame retardants will release halogen free radicals during the combustion process and capture active free radicals in the combustion reaction, thereby interrupting the combustion chain reaction and achieving the purpose of flame retardancy. However, halogen flame retardants may produce toxic hydrogen halide gas when burned, causing certain harm to the environment and human health.
Phosphorus flame retardants mainly form a phosphorus-containing carbon layer during the combustion process, which plays the role of heat insulation and oxygen insulation, preventing further combustion. Phosphorus flame retardants are relatively environmentally friendly, but their flame retardant effect may not be as significant as halogen flame retardants.
Inorganic flame retardants such as aluminum hydroxide, magnesium hydroxide, etc. will decompose and absorb heat when burning, reducing the surface temperature of the material. At the same time, the water vapor released can dilute the flammable gas and play a flame retardant role. Inorganic flame retardants have the advantages of being non-toxic and environmentally friendly, but usually require a larger amount of addition to achieve better flame retardant effects, which may have a certain impact on the performance of EPS Particles.
The flame retardant performance of EPS Particles treated with flame retardant treatment can be significantly improved. For example, it is possible to achieve a certain flame retardant rating, such as Class B1 or Class B2. In practical applications, EPS Particles products with appropriate flame retardant properties can be selected according to different needs.
However, it should be noted that even flame-retardant EPS Particles may be ignited or lose their flame-retardant effect when encountering a strong fire source or burning continuously for a long time. Therefore, when using EPS Particles, it is still necessary to take appropriate fire prevention measures, such as keeping away from fire sources and enhancing ventilation, to ensure safety.
In short, the flame retardant performance of EPS Particles can be improved by adding flame retardants, but it still needs to be treated with caution during use to fully exert its flame retardant effect and ensure safe use.
