Zerogen® 50 SV

Technical DataSheet | Supplied by Huber Engineered Materials

Zerogen® 50 SV by Huber Engineered Materials is a magnesium hydroxide (≥99 % (untreated base)) grade. Acts as a flame retardant and smoke suppressant. Present as odorless white powder. Provides excellent fire retarding and smoke suppression performance for thermoplastic or crosslinked polymer 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. Suitable for use in compound applications where excellent electrical properties are needed, such as in cable insulation materials and fire-rated EVA compounds. Zerogen® 50 SV by Huber Engineered Materials complies with Toxic Substances Control Act (TSCA) Inventory, Canada Domestic Substance List, Canada Non-Domestic Substance List and Mexico National Inventory of Chemical Substances (INSQ).
