Magnesium Hydroxide Magnesium hydroxide is the second largest sales volume of inorganic hydroxide flame retardants. It is a white to light white lens powder with a relative density of 2.4 and a Mohs hardness of 3.0. When heated to above 450°C, the weight will be reduced by 30.9% (mass fraction) due to the loss of water. When magnesium hydroxide is used as a flame retardant, its purity requirements …

Aluminum Hydroxide (ATH) Aluminum hydroxide is one of the most widely used flame retardants. It is a non-toxic, white to light white powder with a relative density of 2.42 and a Mohs hardness of 3.0. When the temperature is heated to higher than 320°C, aluminum hydroxide loses 34.6% of its weight due to water loss. For polymers whose processing temperature is lower than the decomposition temperature of …

Ways to achieve flame retardancy Gas phase flame retardant mechanism. That is, it suppresses the freedom of chain growth in the combustion reaction and exerts a flame retardant effect. Condensed phase flame retardant mechanism. It prevents the thermal decomposition of the polymer in the solid phase and prevents the polymer from releasing combustible gas. Interrupt the heat exchanger management. That is, the hea…
