Flame retardants are additives that give flammable polymers flame retardant functions, and are mainly designed for polymer flame retardant materials; there are many types of flame retardants, which are divided into additive flame retardants and reactive flame retardants.
Nowadays, using flame retardants to reduce the incidence of fires has gradually become the key to people’s fire prevention. With the improvement of people’s awareness of environmental protection, safety, and health, the environmental protection requirements for flame retardants are getting higher and higher. In the future, countries around the world will take environmentally friendly flame retardants as the key points of research and development and application, and strengthen supervision on the safety of flame retardant use. So, what issues should be paid attention to when using flame retardants?
1. Conduct comprehensive toxicity assessments on flame retardants suspected of being harmful to human health and the environment, and strictly control their production, use, and ridicule. Once confirmed to be unsuitable for use, production and sales should be stopped. For example, tris(dibromopropyl) phosphate was once a widely used and very effective flame retardant, but it was later found to be carcinogenic and has been banned in many countries.
2. The impact of newly developed flame retardant products on human health, safety and the environment has been studied and evaluated as a whole. Detailed information on the above aspects can be provided to ensure the safety of production and use.
3. On the one hand, people are working hard to improve and enhance the safety level of existing flame retardants and flame retardant materials, and on the other hand, they are working hard to develop new environmentally friendly flame retardants (such as halogen-free flame retardants) and gradually promote their use (such as the global halogen-free flame retardant polypropylene has reached about 20% of the total amount of flame retardant polypropylene). It is believed that the development of new flame retardants will ensure the use of flame retardant materials, which can not only reduce fire hazards, but also minimize the impact on the environment.
