In modern technology, high vacuum environments are essential for many advanced devices and processes. Whether it’s electron microscopes, nuclear accelerators, or high vacuum coating technologies, one critical material is indispensable: high vacuum diffusion pump oil. And MY 705 is a star product in this field.
Ultra-Low Saturated Vapor Pressure (<6.65×10⁻⁸ Pa):
The stability of a high vacuum environment depends heavily on the oil’s saturated vapor pressure. MY 705’s ultra-low vapor pressure effectively prevents oil vapor backflow, ensuring long-term stable operation under ultra-high vacuum conditions.
Excellent Thermal Stability (Flash Point ≥243℃):
Under high temperatures, ordinary oils can crack and produce contaminants. MY 705’s outstanding thermal stability allows it to withstand high-temperature operations, extending equipment lifespan.
Wide Temperature Adaptability (Pour Point ≤-18℃):
Whether in extreme cold or high-temperature environments, MY 705 maintains excellent fluidity, ensuring stable equipment performance under various conditions.
Scientific Equipment: Electron microscopes, nuclear accelerators, synchrotron radiation light sources, etc.
Industrial Manufacturing: High vacuum coating, OLED screen production, precision optical coatings, etc.
New Energy and Materials: Photovoltaic module encapsulation, semiconductor material preparation, etc.
MY 705 is not just the “invisible guardian” of high vacuum technology but also a driving force behind technological progress. Choosing MY 705 means choosing unparalleled vacuum performance and reliable technical support!
