Description

Trilauryl Trithiophosphite is a specialized organophosphorus compound widely utilized as a high-performance stabilizer and antioxidant in polymer chemistry. Its primary value lies in its ability to effectively scavenge free radicals and decompose hydroperoxides, thereby significantly enhancing the thermal and oxidative stability of various synthetic materials. This makes it an essential additive for manufacturers in the plastics, rubber, and lubricant industries seeking to extend product lifespan and maintain performance under demanding conditions. The compound is recognized under the CAS registry number 1656-63-9.

Application

• Primary antioxidant and stabilizer for polyolefins (e.g., PP, PE) to prevent thermal degradation during processing and end-use.
• Synergistic co-stabilizer in combination with phenolic antioxidants and phosphites for enhanced polymer performance.
• Stabilizing agent for synthetic rubbers and elastomers to improve resistance to heat aging.
• Additive in lubricant and grease formulations to inhibit oxidation and reduce sludge formation.
• Stabilizer for adhesives and sealants to maintain viscosity and adhesive properties over time.
• Protective agent in specialty coatings and resins to prevent yellowing and embrittlement.

Quality Control

Our Trilauryl Trithiophosphite is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by titration and identification by FT-IR, to confirm it meets stringent specifications. A detailed Certificate of Analysis (COA) documenting purity, color, and other critical parameters is provided with every shipment to support your quality assurance processes.

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 light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat, sparks, and open flame. For long-term storage, consider maintaining under an inert gas blanket such as nitrogen to preserve efficacy.
