Vinyl silicone oil, also known as end vinyl polydimethylsiloxane, is a highly versatile silicone fluid that serves as a critical intermediate in numerous industrial sectors. Characterized by its methyl silicone oil base and the presence of reactive vinyl groups at its molecular terminals, this chemical offers a unique combination of desirable properties. NINGBO INNO PHARMCHEM CO.,LTD. is a dedicated provider of high-purity vinyl silicone oil, ensuring that our clients have access to a reliable source for their advanced material needs. This article delves into the essential aspects of vinyl silicone oil, from its fundamental characteristics to its wide-ranging applications.

The core value of vinyl silicone oil lies in its dual nature: it possesses the inherent qualities of methyl silicone oil, such as excellent smoothness, limpness, brightness, and resistance to temperature variations, while its terminal vinyl groups provide exceptional reactivity. This reactivity is key to its use in various chemical reactions, most notably addition curing processes. When catalyzed, the vinyl groups readily react with compounds containing Si-H bonds, forming stable Si-C linkages. This ability to form strong covalent bonds is what makes it invaluable for creating robust polymer networks. Understanding the vinyl silicone oil chemical properties is crucial for formulators.

The vinyl silicone oil applications are extensive. In the rubber industry, it is a principal raw material for producing high-temperature vulcanizing (HTV) silicone rubber and liquid silicone rubber (LSR). For HTV, it enhances hardness and strength. For LSR, it is the primary component for injection molding processes, yielding products with excellent dimensional stability and surface finish. Beyond rubber, vinyl silicone oil is employed to modify plastics, resins, paints, and coatings. By reacting with organic polymers like polyurethanes, it imbues these materials with improved resistance to weathering, aging, and UV radiation, thereby extending their lifespan and performance.

The availability of vinyl silicone oil in various viscosity grades, such as 100 cSt, 350 cSt, 1000 cSt, up to 165,000 cSt, allows for precise formulation control. Choosing the correct vinyl silicone oil viscosity is essential for achieving optimal processing characteristics and desired end-product properties. Whether it's for molding intricate shapes with LSR or achieving specific rheological properties in a coating, the viscosity plays a significant role.
