PU Flame Retardant For External Wall Heat And Acoustic Insulating Board UL94-V0 Class B1

External wall insulation refers to a structural layer composed of insulation materials , which plays a role of thermal insulation in the external thermal insulation hollow brick knotting nail system. The best way to deal with a fire is to prevent it from overthrowing, so that the fire of the stars cannot be burned. Obviously, the most direct and effective way to build a safe and fireproof outer wall insulation layer is to use flame retardant insulation materials.

1. Fire in high-rise buildings is not easy to extinguish.

2. Flame retardant materials prevent the spread of fire and win rescue time. The flame-retardant material is not completely incombustible, but it is not easy to burn. It can withstand tens of minutes or even hours of fire, slow down the spread of fire, and alkali-resistant glass fiber mesh cloth wins valuable rescue time for firefighters.

3. Flame retardant materials reduce the generation of poisonous smoke and reduce casualties. In the fire, the glass fiber cloth will produce a large amount of toxic smoke due to insufficient combustion. The toxic smoke is one of the important reasons for the death of the fire. Current flame retardant materials can simultaneously achieve flame retardant, smoke suppression and toxicity reduction effects, and do not generate extremely toxic or unusual combustion products. The fire safety of flame retardant materials is higher than that of similar non-flame retardant materials in many aspects. When the former burns, the amount of smoke and toxic gas generated can also be lower than the latter.
