Krytox GPL407潤滑脂在40°C時(shí)的機(jī)油粘度為440 cSt，估計(jì)可用溫度范圍為-70–316°C。
Chemours公司生產(chǎn)的Krytox GPL 407潤滑脂使用非熔融增稠劑，而不是普通的Krytopx PTFE。這種從聚四氟乙烯到二氧化硅的變化將潤滑脂的溫度能力從約316°C（600°F）提高到由油的蒸發(fā)/分解溫度確定的上限。Krytox GPL-407由Krytox-GPL-107機(jī)油制成，在適當(dāng)通風(fēng)的情況下，該機(jī)油可以短時(shí)耐受399°C（750°F）和更高的溫度。通過補(bǔ)充/重新潤滑，它可以持續(xù)更長時(shí)間。雖然Krytox GPL-407并不打算在288–316°C（550–600°F）以下的溫度下取代Krytox GPL-200系列，但它確實(shí)將氟化潤滑脂的使用范圍擴(kuò)大到PTFE和Teflon的316°C（600°F? 稠化潤滑脂。Krytox GPL 407比聚四氟乙烯增稠潤滑脂具有更高的油分離度，因此在同等條件下可能不會(huì)持續(xù)那么長時(shí)間。
Krytox GPL407 grease has an Oil Viscosity of 440 cSt at 40°C and the estimated useful temperature range is –70–316 °C.
Krytox GPL 407 grease from Chemours is made using a non-melting thickener, instead of the normal Krytox PTFE. This change from PTFE to silica boosts the temperature capability of the grease from approximately 316 °C (600 °F) to an upper limit determined by the evaporation/breakdown temperature of the oil. Krytox GPL-407 is made from Krytox? GPL-107 oil, which, with proper ventilation, can withstand up to 399 °C (750 °F) and higher temperatures for brief periods. With replenishment/re-lubrication, it can last longer.While Krytox GPL-407 is not meant to replace the Krytox GPL-200 series at temperatures below 288–316 °C (550–600 °F), it does extend the range for using fluorinated greases to beyond the 316 °C (600 °F) limit of PTFE and Teflon? thickened greases. Krytox GPL 407 has higher oil separation than PTFE thickened greases and, therefore, might not last as long under equivalent conditions.
