Description

Dibenzyl Pertetrasulfide is an organosulfur compound with the molecular formula C₁₄H₁₄S₄, functioning as a sulfur donor and vulcanization accelerator. This compound is critical for enhancing the cross-linking efficiency and physical properties of rubber and polymer products. It is primarily needed by manufacturers in the rubber, polymer modification, and specialty chemical synthesis industries seeking to improve material durability and performance.

Application

• Rubber Vulcanization Accelerator: Acts as a sulfur donor and secondary accelerator in the vulcanization of natural and synthetic rubbers, improving cross-link density and heat resistance.
• Polymer Modification: Used to introduce sulfur cross-links into various polymers, enhancing their thermal stability and mechanical properties.
• Lubricant and Grease Additive: Serves as an extreme pressure (EP) and anti-wear additive in industrial lubricants and greases.
• Chemical Intermediate: Employed in the synthesis of other organosulfur compounds and specialty chemicals.
• Sealant and Adhesive Formulation: Imparts improved elasticity and aging resistance to polysulfide-based sealants and adhesives.
• Reclaiming Agent for Rubber: Aids in the devulcanization and reprocessing of scrap rubber.

Quality Control

Our Dibenzyl Pertetrasulfide is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, melting point determination, and impurity profiling. A Certificate of Analysis (COA) documenting all test results 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, and well-ventilated area at a controlled room temperature (15-25°C). This material is easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain stability and prevent degradation. Keep away from strong oxidizing agents and heat sources.
