Information

  Magnesium hydroxide has a high-efficiency flame-retardant effect. What is the specific flame-retardant effect? ​​I will give you a detailed introduction below.

  At present, magnesium hydroxide is widely used as a flame retardant. The flame retardant made of this substance will decompose and release bound water when heated. This process will absorb a lot of heat. This is also the basic principle of magnesium hydroxide flame retardant. . So what are the reasons for choosing magnesium hydroxide as a high-efficiency flame retardant? The following editor will introduce to you.

  1. Price. Magnesium hydroxide is half the price of aluminum hydroxide, and the filling volume is large.

  2. The thermal decomposition temperature of magnesium hydroxide reaches 340℃, which is 100℃ higher than aluminum hydroxide, which is beneficial to increase the plastic processing temperature, accelerate the extrusion speed, improve the plasticization effect, shorten the molding time, and the surface gloss of the product is high. Surface defects will occur, and at the same time, strong peel strength is guaranteed.

  3. Magnesium oxide produced after the combustion and dehydration of magnesium hydroxide is a high-strength, high-heat-resistant material, which can be used as a protective wall to isolate fire sources and toxic and harmful gases. The neutralization ability of magnesium hydroxide and acid is strong, and it can be used as a protective wall. Quickly neutralize the acid gases SO2, NOx, CO2, etc. produced by the plastic combustion process.

  4. Its physical form is granular, which is conducive to uniform distribution, good compatibility with the substrate, and little influence on the mechanical properties of the product.

  The above is the reason why magnesium hydroxide is used as a high-efficiency flame retardant.
