Akrochem HYMOD® M932 SP Flame Retardant
Categories: Other Engineering Material

Material Notes: Product Description: Hymod M932SP and is a high performance, high surface area, low particle size alumina trihydrate (ATH or hydrated alumina) utilized as flame retardants and smoke suppressants in elastomeric applications. ATH is the most frequently used flame retardant in the world. The Hymod M932SP grade is a vinyl silane treated ATH for improved processing and physical properties of thermoset and thermoplastic compounds. ATH is a very effective flame retardant due to its thermodynamic properties which absorb heat and release water vapor. Alumina trihydrate releases its 35% water of crystallization as water vapor when heated above 205°C. The resulting endothermic reaction cools the product below flash point, reducing the risk of fire and acts as a vapor barrier to prevent oxygen from reaching the flame. Typical loadings vary from 20 phr to 150 phr. Because many polymers like polyethylene and polypropylene process above 200°C, these polyolefins should use magnesium hydroxide as a flame retardant filler since its water of hydration releases at approximately 325°C.
