⭐ What Is Silicone Oil?

Silicone oil is a polydimethylsiloxane (PDMS)–based liquid silicone derivative known for its high heat resistance, lubricating properties, and protective capabilities.
Thanks to its chemical structure, it is widely used in both industrial and household applications.

🔧 What Is Silicone Oil Used For?

The main functions of silicone oil are:

✔ 1. Acts as a Lubricant and Reduces Friction

Reduces friction on metal, plastic, rubber, and glass surfaces.

✔ 2. Highly Resistant to Temperature

Can operate without degradation in a wide temperature range such as -50°C to +200°C (up to +250°C for certain grades).

✔ 3. Provides Water-Repellent Protection

Forms a protective barrier against water and moisture on surfaces.

✔ 4. Offers Electrical Insulation

Protects electrical and electronic equipment and reduces the risk of short circuits.

✔ 5. Provides Shine and Surface Protection

Polishes and preserves plastic, vinyl, and rubber surfaces.

✔ 6. Used as an Antifoam Agent

Prevents or eliminates foam formation in industrial processes.

🎯 Purposes of Silicone Oil

Silicone oil is used for the following purposes:

✔ 1. Lubrication

Provides long-lasting lubrication for machine parts, molds, seals, and moving surfaces.

✔ 2. Protection and Maintenance

Protects surfaces against UV, moisture, oxidation, and chemical wear.

✔ 3. Polishing

Gives a clean, glossy appearance to plastic, rubber, and vinyl surfaces.

✔ 4. Electrical Insulation

Its high dielectric strength ensures safety in electrical applications.

✔ 5. High-Temperature Lubrication

Performs reliably even at elevated temperatures.

✔ 6. Foam Control

Used to prevent excessive foam in sectors such as chemicals, textiles, food, and wastewater treatment.
