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.是一種超低蒸氣壓潤(rùn)滑脂，旨在在最苛刻的真空應(yīng)用中提供 的密封。 InfinX HaloVac Ultra 是 Halocarbon 的一種新型潤(rùn)滑脂配方，采用 Halocarbon PFPE 技術(shù)設(shè)計(jì)。 這種潤(rùn)滑脂在超低壓（低至 10 至 –13 mmHg）和寬泛的溫度范圍（–15 °C 至 +300 °C）下提供 的密封性能。 InfinX HaloVac Ultra 提供傳統(tǒng)碳?xì)浠衔锖凸铦?rùn)滑脂甚至其他 的氟化潤(rùn)滑劑 的性能。
