Description

Calcium Didocosanoate is a high-purity metallic soap derived from behenic acid. This compound serves as a versatile and effective functional additive, prized for its excellent lubricating and stabilizing properties in demanding formulations. It is primarily utilized by manufacturers in the plastics, polymer, and specialty chemical industries seeking to enhance product performance and processing efficiency.

Application

• As a high-efficiency internal and external lubricant and release agent in PVC, polyolefins, and engineering plastics processing.
• Functioning as a stabilizer and flow promoter in powder coatings and masterbatch production.
• Acting as a water-repellent and thickening agent in the formulation of greases, waxes, and cosmetic products.
• Used as a surface modifier and dispersing aid for pigments and fillers in composite materials.
• Employed in the production of specialty soaps and corrosion inhibitors for industrial applications.
• Serving as a key component in textile auxiliaries for softening and waterproofing treatments.
