Vinyl Silicone Oil, also known as end vinyl polydimethylsiloxane, is a vital liquid chemical intermediate widely recognized for its exceptional properties and diverse applications. Offered by NINGBO INNO PHARMCHEM CO.,LTD., this product holds a significant position in the creation of high-performance materials across various industries. Its unique structure, featuring reactive vinyl groups at the ends of the polydimethylsiloxane chain, makes it an indispensable building block for advanced chemical syntheses.

The inherent properties of Vinyl Silicone Oil mirror many of the desirable characteristics found in traditional methyl silicone oil, including superb smoothness, a notable limpness, excellent brightness, and remarkable resistance to both high temperatures and general degradation, ensuring long-term durability. However, the presence of the terminal vinyl unsaturation elevates its utility considerably. These vinyl groups exhibit strong reactivity, enabling the molecule to participate in a variety of chemical reactions, most notably the addition reaction with hydrogen silicones under the influence of appropriate catalysts. This forms the basis for the creation of addition-curing silicone systems.

Furthermore, Vinyl Silicone Oil demonstrates enhanced intermiscibility with organic materials compared to standard methyl silicone oils. This improved compatibility facilitates easier integration and reaction with other organic polymers, such as polyurethanes. By containing lively double bonds, it readily reacts with these organic counterparts, paving the way for the development of novel composite materials that combine the benefits of both organic and silicone chemistries. This capability is critical for developing materials with tailored properties for specific demanding applications.

NINGBO INNO PHARMCHEM CO.,LTD. provides Vinyl Silicone Oil in a comprehensive range of viscosities, catering to varied industrial requirements. These include, but are not limited to, viscosities such as 100, 350, 500, 1000, 3500, 5000, 10000, 20000, 65000, and 165000 cSt. Each viscosity grade maintains consistent quality, typically exhibiting a density around 0.97-0.98 g/cm³ and a high flash point, contributing to safe handling and processing. The specified vinyl content and molecular weight are carefully controlled for each viscosity grade, ensuring predictable reactivity and performance in downstream applications.

The applications of Vinyl Silicone Oil are extensive and impactful. One primary use is as a basic raw material in the production of High Temperature Vulcanizing (HTV) silicone rubber. Incorporating Vinyl Silicone Oil into HTV formulations significantly enhances the hardness and tensile strength of the final silicone elastomer, making it suitable for demanding applications requiring mechanical robustness and thermal stability.

Another critical application is in the realm of Liquid Silicone Rubber (LSR). Vinyl Silicone Oil serves as the main material for formulating injection moldable LSR grades. The controlled reactivity of the vinyl groups allows for rapid and efficient curing processes, essential for high-volume manufacturing of intricate silicone parts via injection molding techniques. This enables the creation of flexible, durable, and heat-resistant components used in automotive, medical, and consumer goods sectors.

Beyond silicone rubber manufacturing, Vinyl Silicone Oil is extensively used in the modification of organic materials. Through reactions with polymers like polyurethane, it yields hybrid materials exhibiting superior performance characteristics. These improvements include enhanced weatherability, resistance to aging, improved UV radiation resistance, and significant reinforcement and toughening effects. Consequently, Vinyl Silicone Oil finds widespread application in the modification of plastics, resins, paints, and coatings, leading to products with extended lifespan, improved surface properties, and enhanced mechanical integrity.

Proper storage and handling are essential to maintain the quality and reactivity of Vinyl Silicone Oil. It should be stored airtight at room temperature in a dry, shaded area, kept away from ignition sources and direct sunlight. Contamination by impurities, particularly catalysts or acidic substances, must be strictly avoided to prevent premature reaction or degradation. Packaging options typically include 200 kg drums or smaller 50 kg clean polyethylene plastic barrels, ensuring suitability for various shipment volumes.
