Is the flame retardant fabric a non-burnable cloth?

When it comes to flame retardancy, some people may think of high temperature resistant materials, so what is the difference between the two?

Simply put, high temperature resistant materials can still maintain their original properties under high temperature conditions, such as wear resistance, sealing, etc. That is to say, under high temperature conditions, its chemical properties basically do not change, and at the same time try to ensure that the physical properties do not change.

Flame-retardant materials usually have the characteristics of not burning or not easy to burn in the flame, and extinguishing quickly after leaving the flame, such as some polymer materials containing bromine and phosphorus, which can absorb the free radicals generated by combustion when burning , Hindering the progress of the chain reaction.

In fact, the flame-retardant fabric is not incombustible, it is the performance of the fabric after processing, which can prevent the flame from spreading and automatically extinguish within a certain time.

Therefore, the evaluation of the flame retardant performance of the fabric is usually carried out from the burning rate of the fabric, the burning time (after-burning time and smoldering time) and the length of damage, that is, the shorter the flame burning and flameless burning time, the more damaged The lower the flame retardant performance of the fabric, the better; otherwise, the flame retardant performance of the fabric is poor.
