3M HFE7100清洗剂

3M HFE7100清洗剂是一种无色澄清，无色无味的液体物质，其中甲氧基-九氟代丁烷（C4F9OCH3）含量为99.5％，非挥发组分小于2.0pmm，用以替代氟利昂等“臭氧层破坏性”物质。3M HFE7100清洗剂在新型的的氟氯化碳取代物产品家族中毒性低，以8小时平均工作时间计，它的时间加权平均限制浓度750ppm。主要应用于精密电子仪器、医疗设备的清洗保清洗剂、溶剂，用于取代CFC-113、三氯乙烷、等。
●特点：无色、无味、无毒、不燃烧，ODP值为零；表面张力低、黏度小、蒸发潜热小。
●用途：特殊用途的溶剂、清洗剂、漂洗剂、无水流体、去焊剂和热传递介质，主要用于电子仪表和激光盘片的清洗，颗粒杂物的去除，光学系统及精密场合下清洗。
●优点：由于性能接近CFCs，可使用原有清洗设备，不需要增加设备投资，也不需要对工艺做大的改变。环保，安全！

3M Novec HFE-7100 Engineered Fluid, methoxy-nonafluorobutane (C4F9OCH3), is a clear,colorless and low-odor fluid intended to replace ozone-depleting substances (ODSs) and compounds with high global warming potential (GWP) in many applications. Its physical properties are compared with several other ODS replacement fluid candidates.
This proprietary fluid has zero ozone depletion potential and other favorable environment properties. It has one of the best toxicological profiles of CFC replacement materials, with a time-weighted average exposure guideline of 750 ppm (eight hour average).
The high boiling point and low surface tension of Novec 7100 fluid make it ideal for use in vapor degreasing applications as a neat (pure), azeotropic component or co-solvent part cleaner. In addition, its chemical and thermal stability, non-flammability and low toxicity make it useful for many other industrial and specialty solvent applications (see below).

Materials Compatibility材料相容性
Continuous Exposure长时间材料相容性
Novec 7100 fluid is compatible with most metals and hard polymers. Soft and elastomeric
materials should be limited to compounds that contain the least amount of extractable
plasticizer.
HFE-7100长时间和金属以及一些硬的聚合物兼容。但是对于一些软性聚合物或者橡胶产品必须额外做材料兼容性试验
Non-Continuous Exposure非持续性或者短时间材料相容
Short-term testing of Novec 7100 fluid demonstrates compatibility, after one hour exposure at
boiling temperature, with a wide range of metals, plastics and elastomers, similar to the performance of perfluorinated liquids. Good short-term compatibility with particularly sensitive
plastics such as polycarbonate and PMMA indicates utility in cleaning of assemblies containing
many composite materials. As with most fluorinated liquids, Novec 7100 fluid will absorb into fluorinated plastics and elastomers over longer exposures.
HFE-7100短时间，及沸腾情况下，浸泡1小时，就像全氟液体一样，其可以和绝大多数金属、塑料和橡胶相容。即使是一些敏感性材料例如PC(聚碳酸酯)和亚克力（PMMA），HFE-7100对其在短时间也不会有影响。当然，就像就像全氟液体一样，如果将氟塑料或者橡胶过长时间浸泡，其也会被吸收！
