Description

Di-tert-Butyl Bisperoxysebacate is a high-purity organic peroxide widely recognized for its role as a versatile crosslinking agent and initiator in polymer chemistry. Its primary value lies in providing controlled, efficient free radical generation, which is essential for modifying polymer properties and curing performance. This compound is a critical material for manufacturers in the plastics, rubber, and specialty coatings industries seeking to enhance product durability, thermal stability, and mechanical strength.

Application

• Polymer Crosslinking Agent: Used to create three-dimensional networks in polyethylene, ethylene-propylene rubbers (EPDM), and silicone elastomers, improving heat resistance and mechanical properties.
• Curing Initiator for Unsaturated Polyester Resins: Facilitates the room-temperature or heat-activated curing process in fiberglass-reinforced plastics (FRP) and composite materials.
• Modifier for Thermoplastics: Employed in the controlled rheology of polypropylene (PP) to regulate melt flow index (MFI) during processing.
• Vulcanizing Agent for Rubber: Acts as a co-agent in the peroxide vulcanization of various synthetic rubbers, enhancing crosslink density and compression set.
• Synthesis Intermediate: Serves as a specialized oxidizing agent or free-radical source in fine chemical and pharmaceutical synthesis.
• Adhesive and Sealant Formulations: Imparts enhanced curing characteristics and final strength to high-performance anaerobic and acrylic adhesives.

Quality Control

Our Di-tert-Butyl Bisperoxysebacate is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, active oxygen content, and impurity profiles. A Certificate of Analysis (COA) detailing results for assay, identification, and key physical parameters is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flames. Maintain storage temperature between 15°C and 25°C (59°F and 77°F). Keep away from reducing agents, strong acids, bases, and combustible materials. Due to its nature as an organic peroxide, store in original packaging and segregate from other chemicals.
