Zerogen® 50 SG is a fine particle size alkyl silane-treated Magnesium Hydroxide (MDH) grade with low electrolyte content for wire and cable applications.

Zerogen® magnesium hydroxide products provide excellent fire retarding and smoke suppression performance for thermoplastic or crosslinked polymer compounds. At 330°, they decompose in an endothermic reaction to form water and magnesium oxide. Zerogen products are characterized by high chemical purity, thus suitable for use in compound applications where excellent electrical properties are needed, such as in cable insulation materials.

Zerogen® 50 SG is an alkylsilane-treated magnesium hydroxide product that provides hydrophobicity and superior fire performance when used to make fire-rated polymeric compounds. The surface treatment promotes uniform dispersion of the magnesium hydroxide in the polymer used, providing desirable compounding rheology and enhanced compound performance.
