Are you still looking for a cost-effective flame retardant material? ——Inorganic flame retardant material magnesium hydroxide (Mg(OH)₂) is recommended!
Introduction to magnesium hydroxide
Magnesium hydroxide (Mg(OH)₂) is a white crystal or powder with weak alkalinity and hygroscopicity. The part soluble in water is completely ionized, and the saturated solution concentration is 1.9 mg/L (18°C). Its preparation methods include brucite grinding method and chemical synthesis method (such as calcium hydroxide method, ammonia method, sodium hydroxide method).
Flame retardant principle and advantages of magnesium hydroxide
Flame retardant principle
Magnesium hydroxide decomposes to produce water vapor when heated, absorbs heat, and generates non-corrosive and non-toxic magnesium oxide. This decomposition process:
Increases the decomposition temperature of the material;
Covering the surface of the polymer to isolate the air;
The water vapor produced by the decomposition dilutes the oxygen and effectively inhibits combustion.
Advantages
Environmentally friendly and non-toxic: no harmful gases are released, and it is environmentally friendly.
Highly efficient smoke suppression: reduce combustion smoke and improve safety.
Multifunctionality: As a flame retardant, it also has additional functions such as desulfurization, moisture absorption, and corrosion prevention.
High decomposition temperature: suitable for various processing conditions and shortens production time.
