产品介绍
Krytox 157 FS（H, M, L)
Krytox 157 FS润滑剂不溶于大多数常见的有机溶剂。 它也不易燃。 脱羧在加热到约170°C（338°F）以上时发生，并在200°C（392°F）时剧烈。 形成的产物似乎是混合物，但主要是Krytox氟化油的加氢封端版本。 其碱金属盐在水的存在下脱羧发生在较低的温度下，并产生基本上被氢封端的纯净聚合物。
Like the other Krytox? fluorinated oils, Krytox 157 FSlubricant is insoluble in most common organic solvents. Itis also nonflammable. Decarboxylation occurs on heatingabove about 170 °C (338 °F) and becomes vigorousat 200 °C (392 °F). The product formed appears to bea mixture, but is mainly a hydro-endcapped version ofKrytox fluorinated oil. The decarboxylation of its alkalimetal salts in the presence of water occurs at lowertemperatures and yields essentially pure polymers end cappedwith hydrogen.
