Description

Tetravinylsilane is a highly reactive organosilicon compound with four vinyl groups bonded to a central silicon atom, serving as a versatile building block in advanced material synthesis. Its core value lies in its ability to act as a cross-linking agent and a precursor for silicon-containing polymers and hybrid materials, enabling the creation of products with enhanced thermal stability and tailored mechanical properties. This chemical is essential for R&D and production in the silicone, specialty polymer, and advanced coatings industries, where precise molecular architecture is required.

Application

• Cross-linking Agent: Used in the production of heat-cured silicone rubbers and resins to improve mechanical strength and elasticity.
• Precursor for Silsesquioxanes (POSS): A key monomer for synthesizing polyhedral oligomeric silsesquioxanes, which are used as nanoscale additives to enhance the thermal and mechanical properties of high-performance plastics and composites.
• Surface Modification: Employed to introduce vinyl functional groups onto silica or other inorganic surfaces for improved compatibility with organic polymer matrices.
• Specialty Polymer Synthesis: Acts as a comonomer in the development of vinyl-functionalized polysiloxanes and other specialty silicone copolymers.
• Adhesive & Sealant Formulations: Incorporated into formulations to promote adhesion and curing in high-performance industrial adhesives and sealants.
• Research & Development: Utilized in academic and industrial labs for exploring new silicon-based organic-inorganic hybrid materials and dendrimers.

Quality Control

Our Tetravinylsilane is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including assay by GC, verification of identity, and testing for key impurities. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and ignition points. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C to maintain stability and minimize evaporation. Keep away from strong oxidizing agents.
