Description

Vinyltris(tert-Butylperoxy)Silane is a highly reactive organosilane compound containing multiple tert-butylperoxy groups, serving as a critical crosslinking agent and initiator in polymer chemistry. Its unique structure provides exceptional efficiency in initiating free-radical polymerization and grafting reactions, enabling the formation of robust, crosslinked polymer networks. This product is essential for manufacturers in the silicone rubber, adhesive, and specialty polymer industries seeking to enhance material properties such as thermal stability, mechanical strength, and adhesion.

Application

• Crosslinking Agent for Silicone Rubber: A key component in peroxide-cured High-Temperature Vulcanized (HTV) and Liquid Silicone Rubber (LSR) formulations to achieve optimal tensile strength and elasticity.
• Adhesive and Sealant Formulations: Used as a curing initiator in one-part and two-part silicone adhesives and sealants, providing deep-section cure and excellent bond strength.
• Polymer Modification and Grafting: Facilitates the grafting of vinyl groups onto polymer backbones or inorganic surfaces to modify surface properties and improve compatibility.
• Wire and Cable Insulation: Employed in the crosslinking of polyethylene and other polymers for wire and cable jacketing, enhancing thermal and chemical resistance.
• Composite Material Production: Acts as a coupling agent and initiator in fiber-reinforced plastics and mineral-filled composites to improve interfacial adhesion.
• Specialty Coating Resins: Initiates curing in radiation-curable or thermally-cured coatings, films, and encapsulants for electronic components.

Quality Control

Every batch of Vinyltris(tert-Butylperoxy)Silane is manufactured and tested under strict quality management systems. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing key parameters such as active oxygen content, purity, and peroxide concentration to guarantee batch-to-batch consistency and performance reliability for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its properties of being easily oxidized and highly volatile, it is recommended to store under an inert atmosphere (e.g., nitrogen) at temperatures not exceeding 25°C (77°F). Keep away from incompatible materials such as strong acids, reducing agents, and heavy metal compounds. Observe all local regulations for storing organic peroxides.
