Advantages of aluminum hydroxide flame retardant products

There are many series of flame retardants. For those who are familiar with us, we should know that aluminum hydroxide powder, magnesium hydroxide, and red phosphorus series products are the most good raw materials for flame retardants. Red phosphorus is one of the most good raw materials for flame retardants. This inorganic polymer has a molecular formula of (P4)n. Because it contains only phosphorus, its flame retardant efficiency is very high. The oxygen index of polyamine containing 7.5% red phosphorus can reach 35%. The disadvantage of red phosphorus is that it is easy to absorb moisture, has poor compatibility with resin, and generates PH3 gas, which makes the flame-retardant products dyed, which greatly restricts the direct application of red phosphorus to polymer flame-retardant. Therefore, some people use the method of covering the surface of red phosphorus with a protective film to prepare a microencapsulated red phosphorus flame retardant. It not only has high flame retardant efficiency, but also has less impact on other properties of the polymer, and has good compatibility with resins. No longer have the shortcomings of moisture absorption and PH3 gas generation, and at the same time, low smoke, low toxicity, and thermal stability are also very good. Today, when industrial products are developed and our manufacturing is constantly emerging, various flame retardant products are constantly appearing, and aluminum hydroxide can also be used in large quantities in our daily lives. Its high efficiency, energy saving, low energy consumption, and other advantages are brought into play. It plays an important role, and it is also an emerging product that we should pay attention to and use.
