1,3-DivinyltetraMethyldisiloxane: A Multi-Purpose Silicone Compound
Silicones are a class of synthetic elastomers that are widely used across various industries due to their unique properties such as high heat resistance, excellent electrical insulation, and exceptional chemical stability. Among the different types of silicone compounds, 1,3-DivinyltetraMethyldisiloxane (DVTM) stands out as a versatile compound that finds applications in diverse fields ranging from cosmetics to electronic materials.
Manufactured and supplied by INNO Specialty Chemicals, DVTM is a clear, colorless liquid with a molecular weight of 246.5 g/mol and a boiling point of 161 °C. It is a divinyl-functionalized siloxane that contains four methyl groups and two vinyl groups attached to silicon atoms. Due to the presence of divinyl groups, DVTM can undergo crosslinking reactions with other polymeric or oligomeric compounds, leading to the formation of silicone elastomers with unique properties.
One of the primary applications of DVTM is as a crosslinking agent in the production of silicone rubber. When mixed with a silicone polymer and a curing agent, DVTM can form a three-dimensional network structure through hydrosilylation or condensation reactions, resulting in a highly elastic material with excellent mechanical properties. Silicone rubber made with DVTM is widely used in the automotive, aerospace, and construction industries due to its ability to withstand extreme temperatures, resist chemicals, and provide good sealing and damping properties.
Another application of DVTM is as a vinyl double capping agent in the synthesis of vinyl-terminated silicone fluids. By reacting DVTM with a silanol-terminated polydimethylsiloxane (PDMS) in the presence of a catalyst, vinyl-terminated PDMS can be obtained, which can be further used as a precursor for the production of various silicone materials such as resins, adhesives, and coatings. Vinyl-terminated PDMS made with DVTM has better reactivity and crosslinking efficiency than other vinyl capping agents, making it a preferred choice in many applications.
Apart from these applications, DVTM finds use in the formulation of cosmetic and personal care products as a silicone fluid that imparts a silky, smooth feel to the skin and improves the spreadability of the formulations. It is also used as a release agent, lubricant, and anti-foaming agent in various industrial processes.
In summary, 1,3-DivinyltetraMethyldisiloxane is a versatile silicone compound that finds applications in diverse fields due to its unique properties and reactivity. Manufactured and supplied by INNO Specialty Chemicals, DVTM is a preferred choice for the production of silicone rubber, vinyl-terminated PDMS, and cosmetic formulations. With its excellent performance and cost-effectiveness, DVTM is expected to find more applications in the future, contributing to the advancement of various industries.
