Vertex® 90 SN is a fine particle size vinyl silane-treated Magnesium Hydroxide (MDH) with a high concentration of surface vinyl groups.

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

Vertex 90 SN is a vinyl silane-treated product with high concentration of surface vinyl groups designed to provide excellent compounding rheology and high-quality powder dispersion into such polymers as polyolefins, EPR/EPDM and other elastomers. Vertex 90 SN is suitable for use in making fire-rated thermoplastic, elastomeric and crosslinkable compounds where use of high loading levels of the flame retardant is desired.
