Description

Divinyltetramethyldisiloxane is a versatile organosilicon compound featuring a disiloxane backbone with vinyl and methyl functional groups. This unique structure makes it a valuable reactive intermediate and cross-linking agent in advanced silicone chemistry. It is essential for manufacturers requiring precise molecular architecture in their final products. Key industries that utilize this chemical include silicone elastomers, specialty adhesives, and advanced material science research.

Application

• Key monomer and chain extender in the synthesis of vinyl-functional silicone polymers and resins.
• Cross-linking agent in the production of high-performance silicone elastomers and rubbers (e.g., High-Consistency Rubber, Liquid Silicone Rubber).
• Intermediate for manufacturing silicone-based release coatings, pressure-sensitive adhesives, and sealants.
• Building block for creating custom siloxane copolymers with tailored properties for aerospace and automotive applications.
• Used in hydrosilylation reactions to create modified silicones for personal care and textile treatment formulations.
• Research and development chemical for exploring novel silicone networks and hybrid organic-inorganic materials.

Quality Control

Our Divinyltetramethyldisiloxane is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques to confirm identity, assay, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed to prevent contact with atmospheric moisture. Keep away from heat, sparks, and open flame.
