Hymod® M9400 SP

Hymod® M9400 SP by Huber Engineered Materials is an alumina trihydrate (aluminum hydroxide) grade (99.6% content). Acts as a flame retardant. It is a surface treated, vinyl functionalized, precipitated grade developed for peroxide-cured silicone rubber. Silicone rubber compound does not stick in the mold. Also, it has a narrow particle size distribution for optimum particle spacing in silicone. Optimum particle spacing in turn provides for maximum resistance to carbon tracking. Hymod® M9400 SP is soluble in strong acids and alkalis while insoluble in water. Optimized for maximum performance in high-voltage, silicone rubber insulator compositions.
