Description

2-Butoxyethyl Diisotridecyl Phosphite is a high-performance organophosphite antioxidant and stabilizer. This compound is valued for its effectiveness in preventing oxidative degradation and maintaining the integrity of sensitive materials. It is primarily utilized in the polymer, lubricant, and specialty chemical industries where long-term stability is critical.

Application

• Primary antioxidant and process stabilizer for polyolefins (e.g., PP, PE) and other polymers.
• Synergistic component in stabilization packages for plastics and synthetic fibers.
• Additive in lubricants and greases to prevent oxidation and extend service life.
• Stabilizer in adhesives, sealants, and elastomers to enhance weatherability.
• Intermediate for the synthesis of other specialized phosphite antioxidants.
• Protective agent in transformer oils and other industrial fluids.

Quality Control

Our 2-Butoxyethyl Diisotridecyl Phosphite is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, color, and phosphite content. A Certificate of Analysis (COA) documenting key parameters is provided with every shipment to guarantee consistency and reliability for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening to maintain product integrity. Keep away from strong oxidizing agents.
