A Leader in High
Performance Fluids, Greases and Lubricants
Santovac OS-138™
Polyphenyl Ether Fluid
Summary:
Santovac OS-138™ has exceptionally low volatility and is a thermally stable non-halogenated water white fluid. It preserves the extraordinary resistance to degradation from heat, oxygen, radiation and chemical attack. OS-138™ is designed for applications where extraordinary high temperature and adverse environments are expected. It is compatible with most metals and elastomers commonly used in high temperature applications. OS-138™ is considered essentially nontoxic, when normal hygienic practices are employed.
Advantages:
- Exceptionally low volatility
- High thermal stability
- Resists chemical attack
- High refractive index
- Resists oxidation and radiation
- Excellent resistance to rust and corrosion
- Reduces noise in many applications
- Precious metal protectant
