IOTA 20570 is a low-viscosity polymethylethylsiloxane engineered for high-performance applications where efficient heat transfer and exceptional stability are critical. Its unique combination of properties makes it an ideal choice for demanding industrial and electronic environments.

• Efficient Thermal Management: Characterized by its very low viscosity, this fluid offers superior fluidity and wetting characteristics, enabling rapid heat transfer from sensitive components. Its high flash point ensures outstanding safety and reliability in high-temperature operations.

• Superior Dielectric Properties: This silicone oil possesses excellent dielectric strength, making it highly suitable for use as a cooling and insulating medium in high-power radio frequency equipment, power electronics, and other electrical systems where effective heat dissipation must be coupled with reliable electrical insulation.

• Exceptional Chemical Stability: The fluid demonstrates remarkable chemical inertness. It remains stable and does not react with most strong acids and strong alkalis, with the exception of concentrated sulfuric acid and hydrofluoric acid. This broad chemical resistance ensures long-term performance and integrity in harsh or variable chemical environments.
