For professionals in the rubber industry, sourcing high-performance auxiliary agents is critical for achieving optimal product quality and manufacturing efficiency. Vinyl Terminated Silicone Fluid, a key intermediate in the chemical sector, plays a significant role as a specialized rubber auxiliary agent. As a leading manufacturer and supplier in China, we understand the demands of the rubber industry and provide high-quality vinyl silicone oil to meet these needs. This guide is tailored for procurement managers seeking to understand the value and applications of this versatile product.

The Function of Vinyl Terminated Silicone Fluid in Rubber Manufacturing

Vinyl Terminated Silicone Fluid, bearing the CAS number 68083-19-2, is a reactive silicone polymer that is integral to the production of advanced silicone elastomers. Its primary function in rubber manufacturing stems from its ability to act as a base material for high-temperature vulcanized (HTV) silicone rubber and liquid silicone rubber (LSR). In these applications, the vinyl groups on the silicone chain react with a cross-linking agent (typically a hydrogen-containing silicone fluid) in the presence of a platinum catalyst. This addition-cure mechanism results in the formation of a stable, cross-linked silicone rubber network.

Key Benefits as a Rubber Auxiliary Agent

When used as a rubber auxiliary agent, Vinyl Terminated Silicone Fluid imparts several desirable properties to the final rubber products:

  • Excellent Thermal Stability: Silicone rubber, derived from vinyl silicone fluids, exhibits remarkable stability across a wide temperature range, from very low to very high temperatures. This makes it suitable for applications in extreme environments, such as automotive engine components or industrial seals.
  • Superior Flexibility and Elasticity: The silicone polymer chain provides inherent flexibility, resulting in rubber products that maintain their elasticity even at low temperatures. This is crucial for applications requiring dynamic performance, like seals and gaskets.
  • Chemical Inertness and Durability: Silicone rubber is resistant to many chemicals, ozone, and UV radiation, ensuring long-term durability and performance in demanding conditions. This reduces the need for frequent replacement and maintenance.
  • Electrical Insulation Properties: The dielectric properties of silicone rubber make it an excellent choice for electrical insulation in cables, connectors, and electronic components, protecting against short circuits and environmental damage.
  • Processability: As a fluid, vinyl silicone oil offers good processability, allowing for homogeneous mixing with other rubber compounding ingredients, which is vital for consistent product quality.
