Description

Tris(Tridecyl) Phosphite is a high-performance organophosphorus compound widely recognized for its effectiveness as a stabilizer and antioxidant. This product is crucial for protecting polymers and synthetic materials from degradation caused by heat, light, and oxidation during processing and service life. It is an essential additive for manufacturers in the plastics, rubber, and lubricant industries seeking to enhance product durability and longevity.

Application

• Primary stabilizer and antioxidant for polyolefins (PP, PE) and other polymers.
• Used as a color and melt flow stabilizer in plastic processing to prevent yellowing and maintain processability.
• Effective hydroperoxide decomposer in synthetic lubricants and greases to extend service life.
• Acts as a synergist when combined with primary phenolic antioxidants in stabilization packages.
• Provides processing stability for engineering plastics and elastomers during high-temperature extrusion and molding.
• Used in the formulation of adhesives and sealants to prevent oxidative cross-linking and maintain consistency.

Quality Control

Our Tris(Tridecyl) Phosphite is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high performance. Each lot undergoes rigorous analytical testing, including assay, color, and acidity determination, to meet precise specifications. A comprehensive Certificate of Analysis (COA) documenting purity and key physical-chemical parameters is provided with every shipment to support your quality assurance protocols.

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 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 heat, sparks, and open flames.
