3M HFE-7100 氟化液（九氟丁基甲醚）
Introduction產(chǎn)品簡介
HFE-7100是一種無色澄清，無色無味的液體物質(zhì)，其中甲氧基-九氟代丁烷（C4F9OCH3）含量為99.5％，非揮發(fā)組分小于2.0pmm，專門用以替代氟利昂等“臭氧層破壞性”物質(zhì)。該產(chǎn)品在新型的的氟氯化碳取代物產(chǎn)品家族中毒性最低，以8小時平均工作時間計，它的時間加權(quán)平均限制濃度750ppm。主要應(yīng)用于精密電子儀器、醫(yī)療設(shè)備的清洗保清洗劑、溶劑，用于取代CFC-113、三氯乙烷、四氯化碳等。
●特點：無色、無味、無毒、不燃燒，ODP值為零；表面張力低、黏度小、蒸發(fā)潛熱小。
●用途：特殊用途的溶劑、清洗劑、漂洗劑、無水流體、去焊劑和熱傳遞介質(zhì)，主要用于電子儀表和激光盤片的清洗，顆粒雜物的去除，光學(xué)系統(tǒng)及精密場合下清洗。
●優(yōu)點：由于性能最接近CFCs，可使用原有清洗設(shè)備，不需要增加設(shè)備投資，也不需要對工藝做大的改變。絕對環(huán)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長時間材料相容性
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長時間和金屬以及一些硬的聚合物兼容。但是對于一些軟性聚合物或者橡膠產(chǎn)品必須額外做材料兼容性試驗
Non-Continuous Exposure非持續(xù)性或者短時間材料相容
HFE-7100短時間，及沸騰情況下，浸泡1小時，就像全氟液體一樣，其可以和絕大多數(shù)金屬、塑料和橡膠相容。即使是一些敏感性材料例如PC(聚碳酸酯)和亞克力（PMMA），HFE-7100對其在短時間也不會有影響。當(dāng)然，就像就像全氟液體一樣，如果將氟塑料或者橡膠過長時間浸泡，其也會被吸收！
