Description

Calcium Di(Octacosanoate) is a long-chain fatty acid salt of calcium, also known as calcium montanate. This compound serves as a highly effective and versatile processing aid and lubricant in polymer manufacturing, where it enhances flow properties and mold release. It is primarily utilized by producers of PVC, engineering plastics, and synthetic rubber seeking to improve production efficiency and final product quality. Its inherent properties make it a valuable additive in applications requiring thermal stability and surface modification.

Application

• As an internal and external lubricant in rigid and flexible PVC formulations to improve processing and surface finish.
• As a processing aid and mold release agent in engineering plastics (e.g., ABS, polycarbonate blends) to reduce sticking and cycle times.
• As a flow promoter and dispersing agent in masterbatches and color concentrates for synthetic polymers.
• As a water repellent and hydrophobic agent in coatings, construction materials, and paper treatment.
• As a stabilizer component in polyolefin and PVC systems, contributing to heat stability.
• In the production of synthetic rubber as a processing aid to prevent adhesion to metal surfaces.
• As a cable filling compound ingredient to provide consistent rheological properties.
• In the formulation of polishes and wax blends to enhance texture and application properties.

Quality Control

Our Calcium Di(Octacosanoate) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent composition, purity, and performance characteristics. While we offer standard industrial and technical grades, our processes are designed to meet the stringent requirements of polymer additive applications. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, and melting range are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect flow properties and performance.
