What's good about polypropylene low smoke and halogen free flame retardant? Halogen free flame retardant is one of the fast developing varieties among all kinds of material additives. The purpose of halogen-free flame retardants is to make non flame retardant materials have flame retardant properties, which are not easy to burn or self extinguish under certain conditions. With the continuous progress of halogen-free flame retardant technology, there are more and more kinds of halogen-free flame retardant, and its performance has been greatly improved. Nowadays, the flame retardancy of halogen-free flame retardants mainly includes two types: one can delay the fire and stop the spread of fire; the other is to make the surface of materials rapidly expand and carbonize to form a protective layer. With the continuous improvement of people's awareness of environmental protection and safety, as well as the continuous research and development and progress of new technologies, there will be greater development of halogen-free flame retardant for polypropylene in the future. Haobo editor will tell you about the four development directions of halogen-free flame retardant in the future, hoping to help you.

1) Carbon deposition technology　　
When the polymer is burned, carbon deposition in the condensed phase can achieve the purpose of flame retardant.

2) Smoke abatement technology
Since the smoke emission can be increased by adding halogen-free flame retardant into the polymer, smoke suppression has become an important research topic.

3) Microencapsulation technology　　
Microencapsulation can prevent the migration of halogen-free flame retardant, improve the flame retardant effect, improve the stability and change the formulation.

4) Micronization
In order to improve the fluidity, processability and flame retardant effect of halogen-free flame retardants such as aluminum hydroxide, magnesium hydroxide and antimony oxide, new technologies and new devices are required to make them micronized.
