Description

Butanedioic Acid, Sulfo-, 1,4-Bis(2-Ethylhexyl)Ester, Barium Salt is a specialized organometallic compound primarily used as a high-performance stabilizer and additive. This product is valued for its ability to impart thermal and light stability, particularly in polymer and plastic applications where long-term durability is critical. It serves as an essential component for manufacturers in the plastics, lubricant, and specialty chemical industries seeking to enhance product performance and longevity.

Application

• Polymer Stabilizer: Acts as a heat stabilizer and co-stabilizer in polyvinyl chloride (PVC) and other halogenated polymers to prevent degradation during processing and use.
• Lubricant Additive: Used in the formulation of greases and high-temperature lubricants to improve performance and stability.
• Plasticizer Component: Functions as a secondary plasticizer and stabilizer in flexible PVC products such as cables, flooring, and synthetic leather.
• Specialty Chemical Intermediate: Serves as a key intermediate in the synthesis of other metal-based stabilizers and surface-active agents.
• Coatings and Inks: Imparts stability in certain coating systems and printing inks that require resistance to heat and light.

Quality Control

Our Butanedioic Acid, Sulfo-, 1,4-Bis(2-Ethylhexyl)Ester, Barium Salt is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. Product quality is verified against stringent in-house specifications, with key parameters including barium content, purity, and heavy metal limits. Certificates of Analysis (COA) documenting these results are provided with each shipment and are available upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from strong acids and strong oxidizing agents.
