Stearic acid

1. Appearance: White / slightly yellowish waxy solid (flakes, granules, powder) with a slight oily odor


2. Solubility: Insoluble in water, soluble in hot ethanol and organic solvents


3. Melting point: Approximately 70℃. It melts when heated to exert a lubricating effect


4. Function: Processing aid for cable PVC insulation and sheath compounds, serving as a lubricant and dispersant. It reduces melt friction, improves extrusion smoothness and enhances surface finish


5. Disadvantage: Excessive addition will cause migration to the surface and bloom, impairing the appearance and surface properties of cables


6. It is a saturated fatty acid with moderate thermal stability and is often used in combination with calcium-zinc stabilizers
