Features Of 1-201-100K Dimethyl Silicone Oil

  1. Ultra-high viscosity grade (approximately 100,000 cSt at 25°C) for exceptional film-forming and lubricating performance.

  2. Outstanding thermal stability — maintains integrity over a wide temperature range from –50°C to +200°C.

  3. Chemically inert and hydrophobic, ensuring compatibility with most plastics, elastomers, and metals.

  4. Low surface tension and excellent spreading characteristics for uniform coating and release functionality.

  5. Non-toxic, odorless, and non-volatile — meets general industrial safety and handling requirements.

Typical Applications Of 1-201-100K Dimethyl Silicone Oil

  1. Mold release agent for high-precision rubber, silicone, and polyurethane molding processes.

  2. Base fluid in specialty greases and high-viscosity lubricants for slow-moving or heavily loaded mechanisms.

  3. Viscosity modifier and carrier fluid in personal care formulations requiring long-lasting slip and emolliency.

  4. Dielectric fluid in high-voltage equipment where thermal and electrical insulation stability is critical.

  5. Component in antifoam and defoaming agents for industrial process streams and coatings.
