Optimized for Safety, Reliability, and Long-Lasting Performance
Halocarbon Mechanical Seal Barrier Fluids are synthetic fluorinated oils specifically formulated to lubricate and cool mechanical seal faces in rotary pumps, mixers and agitators. These fluids can be used in both pressurized and unpressurized systems that employ multiple seal arrangements (dual seal and tandem seal).
Halocarbon Mechanical Seal Barrier Fluids are intrinsically nonflammable and nonreactive. Unlike glycol-, alcohol-, hydrocarbon-, mineral oil-, or silicon-based barrier fluids, Halocarbon Mechanical Seal Barrier Fluids are chemically inert, making them ideally suited for use in applications that involve strong acids or bases, flammable solvents, hydrocarbons, corrosive chemicals, strong oxidizers, and reactive gasses.
Key Performance Characteristics:
- Safe to handle, nontoxic
- Clean, no sludge formation
- Nonflammable (no flash or fire point)
- Low temperature fluidity
- High thermal stability
- Compatible with most metals, plastics, and elastomers
- Good heat transfer properties
- Excellent sealing and lubricating properties
Halocarbon Mechanical Seal Barrier Fluids not only allow you to achieve higher safety and reliability standards but also provide an industry-proven solution to mitigate the risk of seal-failures that could result in exposing hazardous process fluids to workers or the environment. Each Mechanical Seal Barrier Fluid can be formulated with an anti-corrosion additive to provide compatibility with a broad range of materials of construction.

When Lewis Acids are Involved, the Choice is Clear
Halocarbon Mechanical Seal Barrier Fluids are manufactured using Halocarbon PCTFE technology, which creates a chemical composition that is less complex and more cost-effective than barrier fluids produced using conventional PFPE-based technology. The inherent simplicity of PCTFE chemistry produces oils that do not contain any oxygen atoms in the chemical backbone. This feature makes Halocarbon Mechanical Seal Barrier Fluids more robust to attack by Lewis acids than PFPE (perfluoropolyether) barrier fluids, which are known to depolymerize when exposed to Lewis acids such as aluminum trichloride, iron or zinc chlorides, iron fluoride, and boron trifluoride.
In all cases, Halocarbon Mechanical Seal Barrier Fluids:
- underwent no weight loss
- did not experience a reduction in viscosity
- had no change in pH, and no increase in acidity
Halocarbon PCTFE Technology is Resistant to Lewis Acid Attack
Test Conditions: Oils heated at 174 oC in the presence of 1.0 wt % anhydrous AlCl3 at 1.0 atm under N2 gas for 24 h. Pressure reduced to 0.1 mmHg to remove volatile organic compounds produced from decomposition.
Halocarbon PCTFE Technology More Stable Than PFPE
