Silicone Diffusion Pump Oil 704 Synonyms: 1. 1,1,5,5-Tetraphenyl-1,3,3,5-tetramethyltrisiloxane 2. 704 silicone diffusion pump Fluid 3. 704 diffusion pump fluid 4. Oil for diffusion pumps Cas No: 3982-82-9 Chemical structure: Diffusion Pump Oil 704 is a colorless transparent oily, single-component fluid designed for high vacuum of 10-7torr (untrapped). It performs well in tough, rugged applications and offers quick pump down, even after exposure to air at operating temperatures. 704 is thermally and chemically stable allowing it to keep pump jets free of tars and hard carbon. Technical Index Chemical composition: Tetramethyl tetraphenyl trisiloxane Ultimate Vacuum, torr (untrapped): 10-7~10-8 Saturated Vapor Pressure, torr : 5x10-8 Specific Gravity: 1.06 ~ 1.07 Viscosity (25°C), cSt: 38±3 Flash Point °C: ≥210 Refractive Index 25°C: 1.5500~1.5600 Congealing Point °C: -35 Molecular Description: 484 Application: Diffusion Pump Fluid 704 can be used in variety of applications, including: Electrical and electronics industry • TV tubes, fluorescent tubes, cathode ray tubes • ordinary bulbs • capacitors • rectifier metallised film vacuum system Optical industry • surface improvements • anti reflective coatings • optical filters and mirrors Metallurgy industry • high-vacuum furnaces • melting, degassing and sintering refractory metals; thick-film deposition Plastics industry • surface improvements • mirror coatings • protective coatings • film coatings Other industries • processing metals and fuels • accelerators • molecular plants • R & D plants • mass spectrometry Others Be used as transmission fluid in high-temperature carriers and various instruments.
