SANTOVAC® FLUIDS
We specialize in the development, manufacture and marketing of "extreme environment" fluids, including high-vacuum fluids. These fluids have minimal or no volatility in high vacuum environments.

Our family of SANTOVAC Fluids falls within the class of Polyphenyl Ethers, or PPEs. PPEs are considered fluids of choice since they not only have low volatility but are resistant to thermal degradation at temperatures reaching 450°C (840°F), the highest in synthetic fluids class. Because of the low volatility and ability to withstand extremely high temperatures, SANTOVAC fluids are suitable for use in equipment that operates in extreme environments, such as those encountered in aerospace applications, and as diffusion pump fluids. In addition to these attributes, these fluids are resistant to chemical and ionizing radiation attack, which makes their use suitable in and around equipment that operates in chemical and ionizing radiation producing environment.

SANTOVAC 5 Polyphenyl Ether
SANTOVAC fluid is often used as a vacuum diffusion pump fluid and operates efficiently, economically, and safely to produce ultra-high vacuum of 5 x 10-10 torr or greater, at 25°C. Diffusion pumps are the most economical and reliable means of reaching such low pressures and SANTOVAC 5 has proven to be, without a doubt, the best pump fluid available for this type of equipment.

SANTOVAC 5P ULTRA Vacuum Pump Fluid
This advanced high purity PPE-derived diffusion pump fluid is used in critical applications that require contamination-free ultra-high vacuum environments. SANTOVAC 5P Ultra accomplishes this through its extremely low back streaming characteristic, which is a consequence of its very high purity.
