Vertex® 100 ST1 is a fine particle size fatty acid-treated Magnesium Hydroxide (MDH) flame retardant for wire and cable applications.

Vertex® magnesium hydroxide products provide excellent fire retarding and smoke suppression performance for the thermoplastic and elastomeric compounds. At 330°, they decompose in an endothermic reaction to form water and magnesium oxide.

Vertex 100 ST1 is a fatty acid-treated product that provides superior fire performance and enhanced mechanical properties when used to make fire-rated polymeric compounds. The surface treatment promotes uniform dispersion of the magnesium hydroxide in the polymer used and enhances compounding and processing throughput, providing enhanced compound performance especially for high-loading applications in halogen-free polyolefins.
