Description

Iron Stearate is a metallic soap of stearic acid, functioning as a versatile processing aid and stabilizer. Its primary value lies in its role as a heat stabilizer and lubricant in polymer processing, where it prevents degradation and improves flow characteristics. This compound is essential for manufacturers in the plastics, rubber, and coatings industries seeking to enhance product quality and processing efficiency.

Application

• As a heat stabilizer and lubricant in the production of polyvinyl chloride (PVC) and other polymers.
• As a water repellent and thickening agent in the formulation of greases, waxes, and polishes.
• As a catalyst deactivator and acid scavenger in polyolefin manufacturing processes.
• As a flow aid and anti-caking agent in powder coatings and various industrial powders.
• As a component in cosmetic formulations, such as makeup and personal care products, for texture modification.
• In the production of specialty papers and coatings to impart specific surface properties.

Quality Control

Our Iron Stearate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, metal content, and physical properties. Certificates of Analysis (COA) are provided to guarantee traceability and batch-to-batch consistency for our industrial partners.

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 product performance.
