DY-201 Two dimethyl silicone oil, chemical name is Polydimethylsiloxane, which formula is (CH3)3SiO[(CH3)2SiO]n-Si(CH3)3, this products is a kind of transparent, colourless polydimethylsilixane liquid, available viscosities ranging from 5cps to 2000000cps.
- Little change in physical properties over a wide temperature span - arelatively flat viscosity-temperature slope, and serviceability from -50°C up to 200°C.
- Excellent water repellency.
- Good dielectic properties over a wide range of temperatures and frequencies.
- Low surface tension - readily wets clean surfaces to impart water repellency and release characteristics.
- Viscosities above 10 mm²/s also exhibit heat stability, oxidation resistance, very low vapour pressures, and high flash point.
- Low order of toxicity
- Essentially odourless
- Soluble in a wide range of solvent
- Non-greasy and non-rancidifying
