Silicone Diffusion Pump Fluid

JPHV-5 

(alternative to Dowsil Dowcorning DC705)

​

Even before Dow corning Diffusion Pump Fluid DC-705 (alternative to Dowsil Dowcorning DC705) had been discontinued since 2013. For the reason you all know, it was not easy for the domestic users to get the Diffusion Pump Oils yet. 

 

By the effort of hardworking Chinese engineers,  Diffusion Pump Fluid (Replacement of DC -705) were developed several years before 2013.

 

Now our Diffusion Pump FLuid (JPHV-5) is purer. The performance of the JPHV-5 almost equals to Dow corning Diffusion Pump Oils DC-705 ’s.

Now, it is more stable, purer with higher C/P. 

​

Same as Dow corning Diffusion Pump Oils DC-705, JPHV-5  is a clear, single component, high viscosity pentaphenyl-trimethyl-trisiloxane silicone fluid manufactured specifically for use in diffusion pumps with an ultra-high vacuum range of 10E-10 torr untrapped and 10E-11 torr trapped.

Applications/Recommended for:

​

• Electron-beam operations;

• For surface treatment equipment. (vapor deposition, sputter, heat treatment) 

• high-vacuum furnaces

• Melting, degassing and sintering

• refractory metals; 

• thick-film deposition

• Space simulation chambers

• Evacuating power and microwave tubes

• Vapor deposition of thin films by sputtering or evaporation in devices and microcircuits
