1.What Is Dimethyl Silicone Oil?

Dimethyl Silicone Oil is a linear polysiloxane polymer with a highly flexible Si–O backbone.

Its molecular structure gives it a unique combination of high temperature resistance, low surface tension, and excellent hydrophobicity.

Common viscosities range from 10 cSt to 100,000 cSt, making it suitable for various formulations—from light-flowing fluids to thick, non-flowing types.

2. Key Properties

Dimethyl Silicone Oil is widely preferred due to its stable and versatile performance:

● Excellent Thermal Stability

Maintains performance from –50°C to 200°C, suitable for both high-temperature and low-temperature environments.

● Good Chemical Inertness

Resistant to acids, alkalis, salts, and most solvents.

● Low Surface Tension

Provides superior spreading, wetting, and defoaming ability.

● Outstanding Lubricity

Reduces friction between surfaces—ideal for plastics, rubbers, and mechanical parts.

● Non-Toxic & Odorless

Safe for use in personal care, cosmetics, food-contact machinery, and medical industries.

3. Main Applications

1) Industrial Lubricants

Used as a long-lasting lubricant for plastic gears, valves, seals, bearings, and precision instruments.

2) Release Agent

Provides smooth release for rubber, plastic, PU, and die-casting molds.

3) Textile and Leather Finishing

Improves softness, smoothness, and hydrophobicity.

4) Defoaming Agent Base Fluid

Widely used as the carrier for silicone defoamers in:

• Fermentation

• Coatings

• Wastewater treatment

• Cleaning products

5) Cosmetics & Personal Care

As an emollient and smoothing agent in:

• Shampoo & conditioner

• Skin creams & lotions

• Makeup primers

6) Electrical and Electronic Industry

Used as an insulating fluid and moisture-proof protective coating.
