Primary Chemistry:
InfinX HaloVac® 250 is a versatile vacuum pump fluid oil that offers universal material compatibility across a wide range of applications.
InfinX HaloVac® 250 is a multifunctional perfluoropolyether (PFPE) vacuum fluid engineered by Halocarbon for demanding applications requiring exceptional thermal stability, low volatility, and broad material compatibility. Designed for use in mechanical vacuum pumps, instrument fluids, hazardous chemical processes, and more, HaloVac® 250 maintains consistent viscosity across a wide temperature range from -42°C to 195°C while resisting chemical breakdown in reactive environments. HaloVac® 250 also offers excellent compatibility with elastomers, plastics, and metals.
Thermal stress and fluid degradation in high-temperature conditions
High volatility of traditional fluids, such as hydrocarbons, silicone, etc.
Poor material compatibility of fluids with plastics, polymers, metals, or elastomers
Reduced operational efficiency from the chemical breakdown of fluids
Rust or corrosion of equipment parts
High vacuum applications
Mechanical vacuum pumps
Instrument fluid
Chlorine service
Oxygen service
Nitrous oxide service
Semiconductors
Hazardous industrial processes
