Description

Calcium Bis[3-(Dodecylthio)Propionate] is a specialized organosulfur compound widely used as a high-performance stabilizer and antioxidant in polymer formulations. Its primary value lies in its ability to effectively scavenge free radicals and decompose hydroperoxides, thereby significantly extending the service life of sensitive materials. This product is essential for manufacturers in the plastics, rubber, and lubricant industries who require reliable protection against thermal and oxidative degradation.

Application

• Polymer Stabilizer: A primary antioxidant and metal deactivator in polyolefins (e.g., polyethylene, polypropylene) to prevent thermal-oxidative degradation during processing and end-use.
• Rubber Industry: Used in synthetic rubber formulations to protect against heat aging and maintain elasticity and mechanical properties.
• Lubricant & Grease Additive: Functions as an antioxidant in industrial lubricants and greases, enhancing their oxidative stability and extending drain intervals.
• Adhesive & Sealant Formulations: Improves the long-term stability and performance of hot-melt and reactive adhesives by preventing polymer chain breakdown.
• Wire & Cable Insulation: Protects the polymeric insulation materials from degradation caused by heat and copper catalysis, ensuring long-term electrical safety.
• Food Contact Materials (FCM): For use in compliant polymer stabilizer systems where regulatory approval is obtained, helping to maintain material properties in packaging.

Quality Control

Our production of Calcium Bis[3-(Dodecylthio)Propionate] adheres to strict quality management protocols. Each batch undergoes comprehensive analysis to ensure it meets precise specifications for purity, melting point, and metal content. Certificates of Analysis (COA) documenting key parameters are provided with every shipment. Our quality system is designed to support compliance with relevant global standards for industrial and specialty chemical applications.

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 material is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent caking or hydrolysis. Due to its susceptibility to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of efficacy, especially after the original container is opened.
