Vertex® 90 SV is a fine particle size Magnesium Hydroxide (MDH) with a proprietary surface treatment. The proprietary surface treatment improves smoke suppression efficiency of the MDH.

Vertex® magnesium hydroxide products provide excellent fire retarding and smoke suppression performance for the thermoplastic and elastomeric compounds.

Vertex 90SV is a magnesium hydroxide with a proprietary surface treatment that provides superior fire performance when used to make fire-rated EVA compounds. The proprietary surface treatment improves smoke suppression efficiency of magnesium hydroxide and increases limiting oxygen index (LOI) of the EVA 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.
