Product Description
IOTA 20566 Vinyl Ethyl Silicone Oil is a high-performance silicone material featuring a molecular chain containing both reactive vinyl groups and flexible ethyl groups. This unique structure provides a combination of excellent reactivity and inherent silicone stability, including high-temperature resistance, superior weatherability, and chemical inertness. It appears as a colorless to light yellow transparent liquid and is soluble in common organic solvents such as toluene, ether, and chloroform. It is widely used across various industries like rubber, plastics, electronics, textiles, and chemicals, serving as a plasticizer, lubricant, release agent, modifier, and key component in cross-linking reactions.

CAS No.: 26710-23-6

Key Properties

• Reactivity: The vinyl groups (content 0.1%-3%, customizable) allow participation in hydrosilylation reactions for cross-linking.

• Wide Viscosity Range: 250-5000 mPa·s at 25℃ to meet different processing needs.

• Exceptional Temperature Resistance: Pour point < -70℃ and flash point >180℃ (open cup) ensure performance across a broad temperature spectrum.

• Superior Stability: Offers good weatherability and chemical inertness.

Primary Applications

1. Silicone Rubber Industry: Acts as a base polymer or reactive diluent in addition-cure Liquid Silicone Rubber (LSR), participating in cross-linking and adjusting processing viscosity.

2. Release Agent: Functions as an efficient release agent for rubber and plastic molding, ensuring easy release without affecting the product surface.

3. Electronics & Electrical: Used in formulating potting compounds, thermally conductive adhesives, and sealing materials for electronic component protection and insulation.

4. Chemical Synthesis: Serves as an intermediate for preparing various modified silicone products via hydrosilylation reactions.

5. Lubrication & Personal Care: Can be used in formulating high-temperature lubricants, hydraulic oils, and as an emollient in cosmetics.

6. Textile Waterproofing: Used as a component in durable water repellents for textiles.
