Description

2-Butoxyethyl Diisodecyl Phosphite is a specialized organophosphite compound widely used as a high-performance stabilizer and antioxidant. Its primary value lies in its ability to prevent degradation and extend the service life of polymers and other sensitive materials by scavenging free radicals and decomposing hydroperoxides. This product is essential for manufacturers in the plastics, lubricant, and specialty chemical industries seeking to enhance product durability and maintain color stability under demanding processing and end-use conditions.

Application

• Primary and secondary antioxidant in polyolefins (e.g., PP, PE) and other polymers.
• Stabilizer for synthetic lubricants and hydraulic fluids to prevent oxidation and viscosity changes.
• Color and melt flow stabilizer during the high-temperature processing of engineering plastics.
• Additive in adhesive and sealant formulations to improve shelf-life and thermal stability.
• Synergistic component in stabilizer systems combined with phenolic antioxidants and UV absorbers.
• Processing aid for PVC and other halogenated polymers to prevent dehydrochlorination.
• Stabilizer for synthetic esters and other base fluids in high-performance lubricant applications.

Quality Control

Our 2-Butoxyethyl Diisodecyl Phosphite is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay, color, acidity, and refractive index determination, to ensure it meets precise specifications for industrial applications. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and consistent performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to exclude moisture. Keep away from strong oxidizing agents.
