High Vacuum Silicone Grease

For attaining a good level of vacuum just as a good quality vacuum pump oil is necessary, the importance of good quality vacuum grease too cannot be denied. High vacuum silicone greases come with abundant qualities and minimal drawbacks for commercial vacuum systems. Made up with a base of silicone high vacuum fluid, the grease looks milky-white in color and compared to ordinary greases, is much stiffer in consistency.

Vacuum grease is applied to O rings, joints and other connections in the vacuum system.

Advantages:
  • Vacuum grease reduces the leak rates associated with O ring and other vacuum connections. Hence, along with being used as a lubricant, it is also used as a sealant for joints in vacuum systems.
  • Water proof and moisture resistant.
  • Corrosion inhibitor.
  • Maintains its consistency, i.e., does not melt or evaporate even in extreme temperatures. Supervac’s High Vacuum grease SV-G9-Silicone can withstand temperatures as low as -25⁰ C to as high as 250⁰ C, making it much better than Apiezon hydrocarbon greases.
  • Preserves the rubber parts and doesn’t let them swell or soften up with heat.
  • Because of being thicker than normal lubricants, it’s not runny and doesn’t contaminate the vacuum system.
  • Recommended for ultra high vacuum systems. Supervac’s SV-G9-silicone is used for vacuums reaching up to 10-9 Torr.
  • Very low vapor pressure, therefore, no oil vapor backstreaming takes place.

In addition to all these advantages, Supervac’s SV-G9-Silicone comes with another advantage – it is very competitively priced. This means that in order to get a world-class quality product, the customer doesn’t have to burn a hole through his pocket.

Silicone Diffusion Pump Oil vs. Hydrocarbon Diffusion Pump Oil


Before the advent of Silicone Diffusion Pump Oils about 20-25 years ago. Hydrocarbon Diffusion Pump Oils ruled the Vacuum Industry. These oils are prepared from base oil that has been distilled from crude oil and purified by Dewaxing and Solvent extraction. This is further purified by additional vacuum distillations. Famous hydrocarbon oils brands are Supervac Hydrocarbon Diffusion Pump Oil(SV-DELTA), Apiezon C and Convoil 20. Silicone Diffusion Pump Oils on the other hand are made by controlled hydrolysis of Silanes, addition of Phenyl groups followed by Distillation. Famous Silicone Diffusion Pump oil brands are Supervac Ultra high Vacuum Silicone Diffusion Pump Oil (SV Sigma) and DC704.

SV-DELTA

 
As it is clear from above that Hydrocarbon Diffusion Pump Oil is suitable in following conditions------------

1)    Cost of operation has to be kept very low.

2)    Operation contaminates oil quickly.

3)    Equipment is very old therefore working life of oil and vacuum level will remain low irrespective of oil used.

For all other applications Silicone Diffusion Pump oil is suitable. Supervac Industries manufactured Silicone Diffusion Pump oil SV-Sigma is one of the best Silicone Diffusion Pump oils available in the world.
