3M氟化液FC-72是无色透明全氟化学品

发布时间:2019-1-28 浏览次数:90

3M氟化液FC-72是无色透明全氟化学品,FC-72具有良好的热稳定性和化学稳定性,而且可以和一些敏感材料相容、不燃、无毒无残留。这一系列独特的性质使得FC-72可以在电子行业有各种不同的应用,包括用于电子行业的质量和可靠信测试。FC-72符合军标Military Speci?cation 883用于真空设备及压力设备的泄露测试。FC-72是一种十分惰性的化学品,故可以用作一些化学反应的介质。

?3M Fluorinert Electronic Liquid FC-72 is a clear, colorless, fully-?uorinated liquid. Like other Fluorinert electronic liquids, Fluorinert liquid FC-72 is thermally and chemically stable, compatible with sensitive materials, non?ammable, practically non-toxic and leaves essentially no residue upon evaporation. This unique combination of properties makes Fluorinert liquid FC-72 ideal for many electronics applications,including quality and reliability testing. Fluorinert liquid FC-72 conforms to Military Speci?cation 883 as a detector ?uid in a vacuum/pressure vessel used in gross leak testing. Its inert nature makes FC-72 liquid a useful reaction medium.
