Description

Bis(2-Butoxyethyl) Decyl Phosphite is a specialized organophosphite compound widely utilized as a high-performance stabilizer and antioxidant. Its primary value lies in its ability to effectively inhibit oxidative degradation and prevent color formation in sensitive materials, thereby extending product shelf life and maintaining quality. This chemical is essential for manufacturers in the polymer, lubricant, and specialty chemical industries who require reliable protection against thermal and oxidative stress.

Application

• As a secondary antioxidant and process stabilizer in polyolefins (e.g., PP, PE) and other polymers to prevent degradation during high-temperature processing.
• As a color stabilizer and antioxidant in synthetic lubricants, greases, and hydraulic fluids to enhance thermal-oxidative stability.
• As a stabilizing agent in adhesives, sealants, and elastomers to prevent premature aging and maintain mechanical properties.
• As an intermediate in the synthesis of more complex phosphite-based antioxidants and specialty chemicals.
• In formulations for PVC and other halogenated polymers to act as a chelating agent and improve long-term stability.
• For the stabilization of fuels and hydrocarbon streams against gum and sediment formation.

Quality Control

Our Bis(2-Butoxyethyl) Decyl Phosphite is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, color, and phosphite content. Certificates of Analysis (COA) documenting key parameters are provided with each shipment to guarantee consistency and performance for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) in the headspace of partially used containers is recommended to preserve efficacy. Keep away from strong oxidizing agents.
