Classification of Flame Retardants

Classification of Flame Retardants

Flame retardants can greatly improve the flame retardant and fire retardant properties of polymer composites, and improve the flame retardant properties of the materials are widely used in transportation, electronic equipment, household and other building materials industry.

Inorganic flame retardants can be divided into additive inorganic flame retardants, thermo-reactive flame retardants and nano-material flame retardants according to the way of adding. Due to the ease of use and better environmental adaptability of additive flame retardants, although they do not enable the material to achieve the function of fully combating the fire, they can still avoid fire accidents, thus giving the people in the fire scene a valuable time to escape.

Reactive flame retardants are stable, long-lasting, and have a low impact on the performance of plastics. The significance of flame retardants in the field of fire safety has been proven. According to the evaluation of the European Commission, the application of fire retardants has led to a 20 percent decrease in the number of people killed in fires in Europe over the past decade.

Inorganic flame retardants usually utilize a number of principles to achieve their flame retardant effect, such as the heat absorption effect, the covering effect, the inhibition of the chain reaction, and the asphyxiating effect of the incombustible gas. Most inorganic flame retardants utilize multiple mechanisms to act jointly to achieve flame retardancy. However, various types of inorganic flame retardants play a role in different mechanisms, and their characteristics are therefore very different.

Inorganic flame retardants can include organic synthetic flame retardants, inorganic flame retardants, nano-materials flame retardants and composite inorganic flame retardants and other four types of inorganic flame retardants, the classification of inorganic flame retardants can also include phosphorus-containing inorganic flame retardants, silicone-containing flame retardants, aluminum hydroxide flame retardant, aluminum hydroxide flame retardant, etc., this paper for the role of the mechanism of the different flame retardants and the advantages and disadvantages of the detailed description.
