Product Q&A

Q:What is stearic acid used for?

Stearic acid is used as an activator, lubricant, thickener, and release agent. It is widely applied in rubber, plastics, personal care, candles, soaps, and food packaging.

Q:What is the difference between triple-pressed and rubber grade?

Triple-pressed grade has higher C18 content (>=90%) and better purity, used in cosmetics, food, and high-end applications. Rubber grade has lower C18 content (60-80%) with more palmitic acid, suitable for rubber processing at lower cost.

Q:What is the recommended dosage in rubber?

Typical dosage is 1-3 phr. It acts as a vulcanization activator, processing aid, and dispersing agent. Specific dosage depends on rubber type and formulation.

Q:Does stearic acid dissolve in water?

No. It is insoluble in water but soluble in organic solvents, oils, and hot alcohols. In water-based systems, it is used as an emulsified form.

Q:What is the shelf life?

24 months when stored in a cool, dry place with packaging sealed. Keep away from moisture, heat, and direct sunlight.
