Features required for flame retardants
Announcer:道尔  Date:2020/1/3 10:26:57  Views:785

        Flame retardants are highly utilized in many industries, and substances that can be used as flame retardants must have flame retardancy and other basic characteristics, which mainly include:

1. Flame retardants will not affect its performance when applied to polymers. For example, under the action of flame retardants, the physical and mechanical properties of plastics will remain unchanged and will not be changed.

2. The decomposition temperature of the flame retardant must be coordinated with the thermal decomposition temperature of the polymer, so that the flame retardant function can be idealized. That is, the flame retardant will not be decomposed during the processing of plastics, otherwise the generated gases and substances will interfere with the performance of the plastics.

3. Durable, stable and reliable. Even after a long time, the effect of flame retardant will not disappear. For example, the flame retardant on fire door is best to be used for a long time.

4. The cost price is not high, because the use of flame retardants is frequent, and the investment is high when the price is high, which is not realistic for many industries.

        In addition, there are other special requirements for flame retardants according to different use conditions. This depends on the specific situation.
