What are the benefits of low-smoke halogen-free flame retardants for polypropylene?

What are the benefits of polypropylene low-smoke, halogen-free, environmentally friendly flame retardants? Halogen-free flame retardant is one of the fastest-growing varieties among various material additives. The purpose of the existence of halogen-free flame retardants is to make non-flame-retardant materials have flame-retardant properties, and they are not easy to burn or self-extinguishing under certain conditions. With the continuous advancement of halogen-free flame retardant technology, there are more and more types of halogen-free flame retardants, and their performance has also been greatly improved. Nowadays, the flame retardant effect of halogen-free flame retardants mainly includes two types: one can delay the fire event and suppress the spread of the fire, and suppress the combustion reaction through a variety of action principles; the other is to make the surface of the material expand rapidly and Carbonization forms a protective layer. With the continuous improvement of people's awareness of environmental protection and safety, and with the continuous development and progress of new technologies, polypropylene halogen-free flame retardants will have greater development in the future. Today, I will talk to you about the future of halogen-free flame retardants. The four major development directions of agents.

1) Carbonization technology

When the polymer burns, carbon formation in the condensed phase can achieve the purpose of flame retardancy.

2) Smoke elimination technology

Since the addition of halogen-free flame retardants to polymers can increase the amount of smoke, smoke elimination has become an important research topic.

3) Microencapsulation technology

Microencapsulation can prevent the migration of halogen-free flame retardants, improve flame retardant effects, improve stability, and change dosage forms.

4) Micronization

Halogen-free flame retardants such as aluminum hydroxide, magnesium hydroxide, and antimony oxide require the use of new technologies and new devices to micronize them to improve their fluidity, processability, and flame-retardant effects.
