Krytox 157 FSH潤滑情況油在40°C時的用戶粘度為703-1055 cSt。Krytox 157 FSH潤滑系統油是杜邦系例Krytox-氟化油的功用化最新版本升級，應用于單單從表面活力劑。該官能團是靠近聚六氟固化劑丙烷端部氟亞甲基上的羧酸基團。Krytox 157 FSH有兩個相對來說較寬的氧原子量位置，即低氧原子量和高氧原子量，有著下具代表性的特點。與其它Krytox氟化油是一樣的，Krytox-157 FSH不溶解大多數種類的無機乙酸丁酯。它也就是不可燃的。當供暖到170°C（338°F）之上時突發脫羧的作用，在200°C（392°F）時變得越來越的劇烈。養成的類產品或許是結合物，但主要是Krytox氟化油的氫端封最新版本升級。堿金屬鹽在水長期存在下的脫羧的作用在較低的溫暖下突發，誕生的水滑石物大多上是純水滑石物，端部包裹有氫。Krytox 157 FSH Oil has a Viscosity of 703-1055 cSt at 40°C.Krytox 157 FSH Oil is a functionalized version of the DuPont series of Krytox fluorinated oils that acts as a surfactant. The functionality is a carboxylic acid group located on the terminal fluoromethylene group of poly(hexafluoropropylene oxide). Krytox 157 FSH is available in two relatively broad molecular weight ranges designated as low and high with the following typical properties. Like the other Krytox fluorinated oils, Krytox 157 FSH is insoluble in most common organic solvents. It is also nonflammable. Decarboxylation occurs on heating above about 170 °C (338 °F) and becomes vigorous at 200 °C (392 °F). The product formed appears to be a mixture, but is mainly a hydro-end-capped version of Krytox fluorinated oil. The decarboxylation of its alkali metal salts in the presence of water occurs at lower temperatures and yields essentially pure polymers end-capped with hydrogen.
