Description

Calcium Dioctyl Bisphosphonate is an organophosphorus compound that functions as a highly effective metal deactivator and stabilizer. Its primary value lies in its ability to chelate metal ions, preventing undesirable catalytic degradation in various industrial processes. This makes it a critical additive for manufacturers in the polymer, lubricant, and fuel industries seeking to enhance product longevity and performance under demanding conditions.

Application

• As a metal deactivator and stabilizer in polyolefin plastics (e.g., polyethylene, polypropylene) to prevent catalyst residue-induced degradation.
• As an additive in lubricating oils and greases to neutralize pro-oxidative metal ions and improve thermal stability.
• As a fuel additive to chelate metal contaminants, reducing gum formation and stabilizing fuel during storage and distribution.
• In industrial water treatment formulations as a scale and corrosion inhibitor, particularly in systems with metal piping.
• As a co-stabilizer in PVC and other halogenated polymers, working synergistically with primary stabilizers to enhance heat stability.
• In the formulation of specialty adhesives and sealants to improve resistance to metal-catalyzed oxidative breakdown.

Quality Control

Our Calcium Dioctyl Bisphosphonate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance as a metal deactivator. A Certificate of Analysis (COA) detailing purity, assay, and key physical-chemical parameters is provided with every shipment to guarantee it meets your technical specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents and strong acids. The product is hygroscopic (moisture-sensitive); ensure the container is properly sealed after each use to prevent absorption of atmospheric moisture.
