| Product Description: Stearic Acid (Rubber Grade) is a mixture of fatty acids composed primarily of octadecanoic (stearic), and hexadecanoic (palmitic 50%) acids to a controlled titer (molecular composition) and acid value (presence of unsaturation). It is a light-colored, waxy solid with a characteristic fatty odor. Akrochem’s stearic acid is available in flake form. The flake form is primarily tallow-based. Stearic acid has FDA status under 177.2600 regulations. Application: Stearic acid is used as a dispersing agent and accelerator activator in rubber compounds. It aids dispersion of pigments and fillers and improves processing since it acts as a stock lubricant and can facilitate mold flow, improve extrusions and aid release. For a higher purity mixture of saturated fatty acids see Akrochem’s Stearic Acid TP (triple pressed). Information provided by Akrochem Corporation |
