Dichloromethyl silicone oil, scientifically known as polydimethylsiloxane, is a common organic silicon polymer fluid and an understated "all-purpose material" in both daily life and industry. It appears as a colorless transparent liquid, odorless and non-toxic, with a smooth touch. Due to its unique molecular structure, it possesses numerous excellent properties and is widely applicable. The molecules are mainly composed of silicon-oxygen bonds, with silicon atoms connected to methyl groups. The molecules have a helical structure, with weak intermolecular forces, resulting in stable and distinctive physical and chemical properties.
The most prominent advantage of this material is its extremely strong temperature stability. It can be used stably for a long time in a wide temperature range of -50°C to 180°C. It does not solidify easily at low temperatures and does not deteriorate easily at high temperatures, making it suitable for various extreme working conditions. At the same time, it has excellent chemical stability, being resistant to acids, alkalis, oxidation, and weathering, and does not react with common chemicals. It also has excellent hydrophobic and dust-proof, as well as anti-shear properties. Dichloromethyl silicone oil of different viscosities have different characteristics. Low-viscosity ones have good fluidity and penetration, while high-viscosity ones have better lubrication and sealing properties.
In addition, dichloromethyl silicone oil has good electrical insulation and physiological inertness, causing no irritation or corrosion to the human body. It is safe and harmless. It is distinct from ordinary mineral oils and superior to most synthetic oils. With its stable, safe, and multi-functional comprehensive advantages, it has become a core auxiliary material across multiple fields such as civilian, industrial, and medical, and is an indispensable basic raw material in the modern fine chemical industry.
