What are the types of inorganic flame retardants?

Flame retardants are also divided into many types according to different processing methods and practical uses. Among them, inorganic flame retardants are a relatively common type of chemical flame retardants. The advantages of inorganic flame retardants include good thermal stability, non-volatility, low smoke generation, no harmful gases, and low cost.

According to the survey, the amount of inorganic flame retardants used in the world now reaches 65% of the total amount of flame retardants used. In my country, there are a wide range of materials that can be used to make flame retardants, and it is also a large country in the production and export of flame retardants. Inorganic flame retardants are functionally divided into unique flame retardants, flame retardant synergists, flame retardant fillers, etc., common aluminum hydroxide, magnesium hydroxide, zinc oxide, borides, etc.

However, after the application of inorganic flame retardants, there will be some defects. For example, textiles treated with inorganic flame retardants have strong flame retardancy, but will gradually weaken after washing with water, and finally have almost no flame retardancy. This is also the area where the development of flame retardants needs improvement in the future.
