Silicone Diffusion Pump Oil IOTA 704, also recognized by its chemical name 1,1,5,5-Tetraphenyl-1,3,3,5-tetramethyltrisiloxane (CAS No: 3982-82-9), stands as a paragon of excellence in the realm of high-vacuum applications. Engineered meticulously, this single-component, colorless, transparent fluid offers unparalleled performance in achieving and maintaining vacuum levels down to 10-7 to 10-8 torr, untrapped. Its robustness makes it ideal for rigorous applications, where it ensures rapid pump-down even after exposure to air at operating temperatures.
The chemical composition of IOTA 704, Tetramethyl tetraphenyl trisiloxane, contributes significantly to its thermal and chemical stability. This stability ensures that the pump jets remain free from tars and hard carbon deposits, extending the life and efficiency of the diffusion pump. With a specific gravity of 1.06 to 1.07 and a viscosity of 38±3 cSt at 25°C, IOTA 704 maintains a perfect balance between fluidity and density, facilitating smooth operation. Its flash point of ≥210°C and congealing point of -35°C make it suitable for a wide range of temperatures, ensuring reliability in diverse environments.
The applications of IOTA 704 are as diverse as they are critical. In the electrical and electronics industry, it plays a pivotal role in the production of TV tubes, fluorescent tubes, cathode ray tubes, and ordinary bulbs, ensuring flawless vacuum conditions for optimal performance. In the optical industry, it contributes to surface improvements, anti-reflective coatings, and the creation of optical filters and mirrors. Metallurgy benefits from its use in high-vacuum furnaces, where it aids in melting, degassing, and sintering refractory metals, as well as in thick-film deposition processes. The plastics industry leverages IOTA 704 for surface improvements, mirror coatings, and protective and film coatings, enhancing the aesthetic and functional properties of plastic products.
Beyond these traditional applications, IOTA 704 finds its way into cutting-edge research and development facilities, accelerators, molecular plants, and mass spectrometry, where its precision and reliability are indispensable. Its ability to withstand extreme conditions while maintaining high vacuum levels makes it a trusted choice for scientists and engineers seeking to push the boundaries of innovation.
