Silicone oil, also known as silicone fluid, is a polymer composed of siloxane bonds, which are connections between silicon and oxygen. Renowned for its excellent heat resistance, weather resistance, and chemical stability, silicone oil maintains consistent viscosity despite temperature fluctuations. Due to its physiological inertness and harmlessness to the human body, it finds use in a range of industrial applications, such as machine lubricants, and consumer products like cosmetics and water-repellent clothing.
Available in various products with differing chemical structures and viscosities, silicone oil must be selected based on the specific application requirements.
Used extensively in manufacturing and industrial applications, silicone oil serves as an electrical insulating oil, lubricating oil, and anti-vibration oil. It's also employed in cosmetics, anti-foaming agents, and water-repellent treatments for textiles and glass. Available in several types, each with unique chemical structures and viscosities, silicone oil is chemically stable and compatible with a wide range of materials due to its low reactivity with metals and other compounds.
Silicone oil, a polymer linked by siloxane bonds between silicon and oxygen, varies based on the atoms or molecules attached to its side chain. Types include dimethyl silicone oil with a methyl group (CH3), methyl phenyl silicone oil with a benzene ring, and methyl hydrogen silicone oil with hydrogen in the side chain. Each type exhibits distinct chemical structures, thus leading to varied properties and applications.
Beyond standard silicone oil, modified varieties exist where the chemical structure of certain parts is altered, expanding its range of applications.
With robust siloxane bonds, silicone oil demonstrates exceptional heat and weather resistance and remarkable chemical stability. Its viscosity remains relatively constant across temperature changes, making it ideal for use in instrument oils and lubricants in the automotive and railway sectors.
Notable for its low surface tension, silicone oil readily spreads over various surfaces, unlike water or general synthetic oils. This unique property, among others, broadens its application scope significantly.
Physiologically inert, silicone oil poses minimal skin and eye irritation risks and is generally safe barring excessive ingestion. However, at temperatures above 150°C in an air atmosphere, it can produce minor quantities of harmful formaldehyde. While stable at high temperatures, certain silicone oils are classified as flammable liquids under the Fire Service Law, requiring careful management and storage in compliance with regulations.
