Amid the rapid development of the fine chemical and electronics industries, low-viscosity methyl silicone oil has become an indispensable base material across numerous sectors due to its outstanding physicochemical properties.

The PDMS-10 cSt methyl silicone oil (polydimethylsiloxane) developed by Jiujiang Shenhai Technology Co., Ltd. provides professional-grade performance for both personal care and industrial manufacturing applications. It is distinguished by its exceptional purity, excellent shear stability, outstanding transparency, and wide operating temperature range.

I. Core Characteristics: The Perfect Balance Between Fluidity and Stability

Low-viscosity methyl silicone oils generally refer to products with a viscosity below 50 cSt. Among them, the 10 cSt grade is widely regarded as the "sweet spot," offering an ideal balance of fluidity, stability, and performance.

Excellent Leveling and Wetting Performance

PDMS-10 cSt has a low surface tension, allowing it to spread rapidly over a variety of complex surfaces and form a uniform lubricating film or water-repellent coating. With a viscosity-temperature coefficient of only 0.56, it maintains remarkably stable fluidity across a broad temperature range, ensuring consistent performance under both high- and low-temperature conditions.

Superior Thermal Stability and Operational Safety

The product features a closed-cup flash point of 211°C, significantly higher than that of ultra-low-viscosity grades such as 5 cSt. This enhanced thermal stability improves operational safety in high-temperature industrial environments. It performs reliably over a temperature range of -40°C to 200°C and exhibits excellent shear stability without significant thermal degradation.

High Purity and Outstanding Physical Properties

PDMS-10 cSt is a clear, transparent liquid that is virtually odorless, non-toxic, and non-greasy. It offers excellent dielectric (electrical insulating) properties, high compressibility, and superior dispersibility, making it suitable for a wide range of demanding applications.

II. Key Application Areas: From Personal Care to Precision Industry

1. Personal Care and Cosmetic Formulations

In cosmetic formulations, PDMS-10 cSt serves as an ideal non-volatile carrier fluid. It imparts a silky, smooth, and dry-touch feel while effectively reducing the greasy sensation commonly associated with skincare products.

Typical applications include antiperspirants, deodorants, hair sprays, cleansing creams, skincare lotions, sunscreens, and tanning products. Its excellent spreadability promotes the uniform distribution of active ingredients while leaving little to no greasy residue on the skin.

2. Electronics, Electrical Applications, and Heat Transfer Media

As electronic devices become increasingly compact and power-dense, efficient thermal management has become more critical than ever. PDMS-10 cSt is widely used as a base fluid for heat transfer media and thermal interface materials, helping fill microscopic gaps between electronic components and heat sinks to improve heat dissipation efficiency.

In addition, its excellent dielectric properties provide long-lasting electrical insulation, protecting circuit boards and electronic components from moisture, dust, and corrosion.

3. Industrial Lubrication and Mold Release

In the plastics, rubber, and metal die-casting industries, PDMS-10 cSt functions as a highly effective mold release agent. It forms a thin, heat-resistant film on mold surfaces, preventing adhesion, improving demolding efficiency, and enhancing the surface finish of molded products.

The product is also widely used as a protective coating for precision instruments and optical lenses, as well as a penetrating lubricant in various mechanical systems.

4. Defoaming and Surface Treatment

Owing to its extremely low surface tension, PDMS-10 cSt rapidly disrupts foam films and suppresses foam formation. As a result, it is widely used as a defoaming and antifoaming agent in chemical processing, paints and coatings, wastewater treatment, and other industrial applications where foam control is essential.
