In the ever - evolving landscape of modern industry and scientific research, the demand for high - precision and high - performance environments is constantly growing. High - vacuum conditions have become a crucial factor, and IOTA 704 high - vacuum diffusion pump oil emerges as a vital component in achieving and maintaining such environments.

At the molecular level, IOTA 704 possesses a unique structure that endows it with special physical and chemical properties. In terms of technical specifications, its performance is impressive. At 25℃, the viscosity is precisely controlled at 38±3cst, ensuring stable fluidity and lubrication within equipment under varying temperature conditions. The refractive index at 25℃ ranges from 1.5500 to 1.5600, and the relative density is between 1.06 and 1.07. These parameters work in tandem to influence its light - transmission and material - related characteristics. The flash point (open cup) is ≥210℃, indicating a high level of safety as it is less prone to combustion risks. With a freezing point as low as -35℃, it can function effectively even in cold environments. The vacuum degree is less than 10⁻⁷ - 10⁻⁸Pa, and the saturated vapor pressure is less than 2x10⁻⁸Pa, demonstrating its excellent resistance to vapor pressure.

Outstanding Performance, Diverse Applications

The allure of IOTA 704 lies in its remarkable performance. As a colorless and transparent oily liquid, it exhibits extremely low saturated vapor pressure, allowing it to maintain stable performance in high - temperature environments. Its good thermal stability ensures that it does not easily decompose or deteriorate during long - term high - temperature operation. Additionally, its good oxidation resistance extends its service life, reducing the frequency of oil replacement and lowering usage costs.

In practical applications, its significance is undeniable. In the high - vacuum metallurgical industry, it provides a stable high - vacuum environment for the smelting process, ensuring the purity and quality of metals. In the electron tube industry, it guarantees the normal operation of electron tubes, enhancing the quality of electronic signal transmission. In light bulb manufacturing, it helps improve the vacuum degree of bulbs, extending their service life. In the field of high - vacuum coatings (films), it supports the uniformity and adhesion of coatings. It also plays a crucial role in atomic energy accelerators, electron microscopes, and displays, driving technological progress in these areas.
