In the realm of specialty chemicals, Vinyl Silicone Oil (CAS: 68083-19-2) stands out for its unique chemical properties and remarkable versatility. As a key chemical auxiliary agent, it serves as a fundamental building block for advanced polymer synthesis and material modification. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier, sheds light on the intrinsic characteristics that make this product indispensable for industrial applications.

Understanding the Chemical Structure and Reactivity

Vinyl Silicone Oil, chemically known as Vinyl Terminated Polydimethylsiloxane, possesses a linear siloxane backbone with vinyl groups (-CH=CH2) attached to the terminal silicon atoms. The general formula often cited is Si-[CH3]2O-[n](CH3)2Si. The presence of these vinyl groups is critical. They are highly reactive and participate readily in addition-cure (hydrosilylation) reactions with compounds containing silicon-hydride (Si-H) bonds, typically in the presence of a platinum catalyst. This characteristic is the basis for its use in forming silicone elastomers, gels, and resins.

The viscosity of Vinyl Silicone Oil can range significantly, from a few centistokes to tens of thousands, depending on the degree of polymerization (represented by 'n' in the formula). This variability allows formulators to select grades that are best suited for their specific processing and application needs. High purity, often exceeding 99.9%, ensures predictable and consistent reactivity.

Key Industrial Applications Driven by Chemical Properties

The chemical attributes of Vinyl Silicone Oil translate into a wide array of industrial applications:

  • Silicone Elastomer Synthesis: It is the primary component for making two-part addition-cure silicone systems. When combined with a cross-linker (a silicone fluid with Si-H groups), it forms silicone rubber that cures at room or elevated temperatures, producing materials with excellent thermal stability, flexibility, and dielectric properties. Buyers seeking silicone rubber raw material often rely on our consistent quality.
  • Hybrid Polymer Development: Reacting Vinyl Silicone Oil with organic polymers like acrylates, epoxies, or polyurethanes creates hybrid materials. These composites exhibit synergistic properties, such as improved flexibility, enhanced weatherability, and greater impact resistance, making them valuable for advanced coatings and sealants. When looking to buy Vinyl Silicone Oil for such modifications, consider its compatibility with your chosen organic resin.
  • Specialty Formulations: It's also utilized in applications like mold-making compounds, electronic potting materials, and as a plastic additive to improve surface properties.
