Description

Lithium Stearate is a white, fine powder belonging to the class of alkali metal salts of long-chain fatty acids. It serves as a versatile and efficient high-temperature lubricant, stabilizer, and thickening agent in demanding industrial formulations. This compound is essential for manufacturers in the plastics, cosmetics, and lubricant industries seeking to improve product performance and thermal stability.

Application

• As a high-temperature lubricant and grease thickener in automotive and industrial applications.
• As a stabilizer and acid scavenger in polyolefin (e.g., PP, PE) production to prevent catalyst residue degradation.
• As a viscosity modifier and opacifying agent in cosmetics and personal care products like creams and lotions.
• As a mold release agent in plastic and rubber manufacturing processes.
• As a water-repellent agent in coatings and construction materials.
• As a component in powder metallurgy for binding and lubricating metal powders.

Quality Control

Our Lithium Stearate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise chemical and physical specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee batch-to-batch consistency and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect flow properties and performance.
