Welcome to purchase magnesium hydroxide from Taixing, a professional flame retardant manufacturer. It is a white, odorless solid that naturally occurs in the mineral brucite and is an effective acid stabilizer, flame retardant, and neutralizer.
We offer both types of products, and there are multiple perspectives to consider. In addition to the suggestions provided here, you can also contact us for more detailed solutions.
and magnesium hydroxide have similar flame retardant mechanisms. Both first undergo endothermic decomposition, releasing water vapor and forming a protective oxide layer. However, MDH has a higher decomposition temperature and better compatibility with high-temperature polymers. If we use data to analyze this point, the decomposition temperature range of ATH is 200–220℃, while that of MDH is around 300–330℃.
This is also similar, since they are both additive flame retardants, the required filler content will be a little higher to achieve the UL94 V-0 rating.
ATH typically requires 30–60% filler, please pay attention to it, larger amount of ATH can significantly affect mechanical properties and density. , which has higher thermal stability, can achieve similar flame retardant effects with lower addition amounts, so it is more economical for high-temperature resins.
As they are both inorganic powders with strong chemical inertness, this point is also related to the temperature they can withstand. Aluminum hydroxide decomposes at high temperatures, which weakens its flame-retardant effect. Considering outdoor or high-temperature conditions, magnesium hydroxide is the better choice.
