Magnesium hydroxide featured.MagShield magnesium hydroxide magnesium hydroxide: see milk of magnesia. , said to be a cost-effective replacement for ATH in flame retardancy and smoke suppression, is featured in this four-page, four-color brochure. MagShield allows processing at a temperature up to 100[degrees]C higher than ATH, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the literature. An increase of as little as 10[degrees] to 30[degrees] is said to significantly improve processing efficiency by increasing extrusion speeds and decreasing mold filling time. MagShield is said to be cost competitive with ATH for many applications, making MagShield the performance and economical choice in flame retardants, according to the literature. MagShield is said to be less abrasive than ATH, resulting in longer mixing and compounding equipment life. This is said to be demonstrated by MagShield's Mohs hardness Mohs hardness Rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised by German mineralogist Friedrich Mohs in 1812. of 2.5 vs. 3.0 for ATH. MagShield is said to exhibit low toxicity and is non-corrosive compared to halogen or phosphorus containing compounds. MagShield produces more char than ATH, resulting in increased effectiveness and less smoke. It contains 31% bound water.
