Divinyltetramethyldisiloxane (DVTMDS)

CAS No.: 2627-95-4 | High Purity Vinyl Silicone Intermediate

Product Overview

Divinyltetramethyldisiloxane (DVTMDS) is an important vinyl silicone intermediate widely used in the synthesis of advanced silicone materials. The molecule contains two reactive vinyl groups attached to a disiloxane backbone, which enables efficient participation in hydrosilylation reactions and polymer modification processes.

Due to its unique molecular structure, Divinyltetramethyldisiloxane plays a key role in the production of vinyl-terminated silicone oils, silicone elastomers, silicone resins, and addition-cure silicone rubber systems. It is especially valuable in platinum-catalyzed curing reactions where stable vinyl functionality is required.

Zibo Chiye Chemical Technology Co., Ltd. supplies high-purity Divinyltetramethyldisiloxane (≥99.9%) with stable quality and reliable global supply capability. Our DVTMDS products are widely exported to international markets including North America and Europe, supporting silicone manufacturers, chemical distributors, and specialty chemical companies.

Molecular Structure

Divinyltetramethyldisiloxane is a disiloxane compound containing two vinyl functional groups. The vinyl groups provide reactive sites that participate in addition reactions with hydride-functional silicones.

Typical molecular structure:

CH?=CH–Si(CH?)?–O–Si(CH?)?–CH=CH?

This structure gives Divinyltetramethyldisiloxane excellent reactivity and compatibility in silicone polymer synthesis.

Key Features

• High purity Divinyltetramethyldisiloxane ≥99.9%
• Highly reactive vinyl functional groups
• Excellent compatibility with platinum catalyst systems
• Stable chemical properties for industrial silicone production
• Low impurity content for high-performance silicone materials

These characteristics make DVTMDS an essential intermediate in modern silicone chemistry.

Applications

Silicone Elastomers

Divinyltetramethyldisiloxane is commonly used in silicone elastomer formulations. The vinyl groups enable crosslinking reactions with hydride-functional silicones, forming flexible and durable elastomer networks.

Addition Cure Silicone Rubber

DVTMDS is widely used in platinum-catalyzed addition-cure silicone systems. It helps control polymer chain structure and improves curing efficiency.

Vinyl-Terminated Silicone Oils

The compound serves as a precursor in the synthesis of vinyl-terminated silicone oils, which are essential components in silicone rubber, sealants, coatings, and adhesives.

Silicone Polymer Modification

Chemical manufacturers use Divinyltetramethyldisiloxane to introduce reactive vinyl functionality into silicone polymers, improving reactivity and performance.

Advantages of High Purity DVTMDS

Using high-purity Divinyltetramethyldisiloxane provides several advantages for silicone manufacturers:

• Improved reaction efficiency
• More stable platinum-catalyzed curing reactions
• Better control of silicone polymer molecular structure
• Reduced catalyst poisoning
• Consistent product performance

These advantages make DVTMDS a key raw material for advanced silicone materials.

Packaging and Storage
