VERTEX 100SV is a magnesium hydroxide product with a proprietary surface treatment that provides superior fire performance when used to make fire-rated compounds. The proprietary surface treatment improves smoke suppression efficiency of magnesium hydroxide and increases limiting oxygen index (LOI) of the compound. As a result, lower magnesium hydroxide loading level can be used leading to enhanced rheological and processing performance, and improved compound mechanical properties. The surface treatment also promotes compatibility of the magnesium hydroxide with the polymer and high quality of dispersion. VERTEX 100SV is ideal for applications requiring fire retardancy and smoke suppression without compromising on other performance aspects. Its unique surface treatment allows for lower loading levels and enhanced dispersion, leading to improved mechanical properties and processing.
