As industries continue to evolve, the demand for high - performance vacuum solutions is on the rise. Silicone Diffusion Pump Oil IOTA 705 emerges as a key player, unlocking new possibilities in vacuum technology with its unique properties.
IOTA 705 has several alternative names, including 705 Diffusion Pump Fluid and Phenylmethylsiloxane Oligomers. It is identified by the CAS number 3390 - 61 - 2 and has a chemical structure based on pentaphenyl trimethyl trisiloxane. This single - component, colorless, and transparent oily fluid is specifically formulated for ultra - high vacuum applications. In an untrapped state, it can attain a vacuum range of 5×(10 - 9～10 - 10) torr and demonstrates good radiation resistance.
The technical parameters of IOTA 705 are precisely defined to ensure enhanced performance. The ultimate vacuum in an untrapped condition is 1×(10 - 9～10 - 10) torr. The extrapolated vapor pressure at 25°C is 3×10 - 10. The specific gravity lies within the range of 1.090 - 1.100. The viscosity values are 170 - 175 cSt at 25°C and 61 - 64 cSt at 40°C. The flash point is at least 243°C. The refractive index at 25°C is between 1.5765 and 1.5785. The congealing point is no greater than - 14～ - 18°C, and the molecular description is 546. These precise parameters enable it to perform reliably under different operational scenarios.
IOTA 705 has a wide array of applications to meet the diverse needs of various industries. In the electrical and electronics sector, it is utilized in TV tubes, fluorescent tubes, cathode ray tubes, ordinary bulbs, capacitors, and rectifier metallised film vacuum systems. In the optical field, it is involved in surface treatments, anti - reflective coatings, optical filters, and mirrors. In metallurgy, it is used in high - vacuum furnaces, melting, degassing, and sintering refractory metals, as well as thick - film deposition. In the plastics industry, it is applied for surface improvements, mirror coatings, protective coatings, and film coatings. It also finds applications in metal and fuel processing, accelerators, molecular plants, R & D facilities, and mass spectrometry. Moreover, it can function as a transmission fluid in high - temperature carriers and various instruments.
