InfinX HaloVac Ultra is an ultra-low vapor pressure grease designed to provide superior seals in the most demanding vacuum applications. InfinX HaloVac Ultra is a new grease formulation from Halocarbon and is engineered using Halocarbon PFPE technology. This grease provides superior sealing performance at ultra-low pressures (down to 10 to –13 mmHg) and across a broad range of temperatures (–15 °C to +300 °C). InfinX HaloVac Ultra provides performance that is unsurpassed by conventional hydrocarbon and silicone greases, and even other leading fluorinated lubricants.是一种超低蒸气压润滑脂，旨在在最苛刻的真空应用中提供 的密封。 InfinX HaloVac Ultra 是 Halocarbon 的一种新型润滑脂配方，采用 Halocarbon PFPE 技术设计。 这种润滑脂在超低压（低至 10 至 –13 mmHg）和宽泛的温度范围（–15 °C 至 +300 °C）下提供 的密封性能。 InfinX HaloVac Ultra 提供传统碳氢化合物和硅润滑脂甚至其他 的氟化润滑剂 的性能。
