HELISOL® 10A
- Chemical Family
- Silicones
HELISOL® 10A is a linear, non-reactive polydimethylsiloxane with a viscosity of approximately 10 mm²/s. Its unique chemical structure sets it apart from organic materials like mineral oils, giving it exceptional properties. HELISOL® 10A is a clear, odorless, and colorless liquid.

- Safety Note
- Reactivity; Chemical stability
- Possibility of hazardous reactions No hazardous reactions known if properly stored. When it is used as intended (up to 425 °C), amounts (< 25%) of a mixture of D-cyclic siloxanes (including octamethylcyclotetrasiloxane (D4, CAS 556-67-2) and decamethylcyclopentasiloxane (D5, CAS 541-02-6)) are formed. This depresses the flash point and increases the vapor pressure.
- Conditions to avoid
- Permeation of oxygen and water or any contamination at operating temperature.
- Incompatible materials
- None known.
- Hazardous decomposition products
- When it is used as intended (up to 425 °C), it has been found that in the absence of oxygen and after relatively long operating times, extremely small quantities of methane, hydrogen and volatile silanes (tetramethylsilane, CAS 75-76-3 and trimethylsilane, CAS 993-07-7) may be produced, which further depress the flash point.
