概述
Opteon™ SF-10 热传导液是一个清澈，透明，不可燃，热稳定性好液体体工质。它满足了全球热传导液市场中对低环境效应液体的要求。 Opteon™ SF- 10 的沸点为 110℃(230℉)，零 ODP，不破坏臭氧层，同时它的全球变暖潜值(GWP)非常低，只有 2.5（100年 ITH）计。它的一系列性能和良好的环境特性使得Opteon™ SF-10 可以做为目前使用的 PFCs, PFPEs, HFEs, HFCs 和 HCFCs 的替代产品，同时又可以减少温室效应气体的排放。
典型应用：
Opteon™ SF-10 做为热传导液的商业化应用包括非相变的热传导液在半导体制造，盐水冷却液，绝缘液体，燃料电池，反应器冷却液，热交换器，干燥器，涡轮，热泵和设备的检漏液（如鼓泡测试）等。它推荐的操作温度工作范围从-85-105℃(-112-221 ℉)。
Opteon™ SF-10 的优势
1） 低环境效应，它是基于 HFO 技术，因此它的 GWP很低，比常用的 PFCs, PFPEs, HFEs, HFCs 和HCFCs 要低很多；
2） 可以非常方便地应用天现有的设备中，实现无缝转换，从而减少系统的工作条件波动，缩短认证过程；
3） 也其它液体的互溶性很好，可以实现无差别的替换其它高 GWP 的液体；
4） 密度较低，在同样充注重量情况下体积更大，成本低；
5） 粘度低，减少功率的消耗，运行费用低；
6） 低的介电损耗常数，所以可以用于浸没式冷却方式；
7） 安全暴露极限高，工作安全性好；
安全，毒性和环境特性
Opteon™ SF-10 热传导液是一个不可燃的液体，它的热稳定性在 175℃(347℉)以下是可以使用的。它在哺乳动物研究中表现出非常好的安全特性。它的职业暴露极限是 500ppm。它不具有皮肤和眼部刺激特性。在环境特性测试中 Opteon™ SF-10 对水生生物也很安全。更多的数据请参看化学品安全数据手册(MSDS)

Opteon™ SF-10 heat transfer fluid is a clear, transparent, nonflammable liquid working fluid with good thermal stability. It meets the global heat transfer fluid market's demand for low environmental impact fluids. Opteon™ SF-10 has a boiling point of 110 °C (230 °F), zero ODP, does not deplete the ozone layer, and has a very low global warming potential (GWP) of only 2.5 (100-year ITH). Its combination of properties and good environmental profile makes Opteon™ SF-10 a replacement for currently used PFCs, PFPEs, HFEs, HFCs and HCFCs, while also reducing greenhouse gas emissions.
Typical Applications
Commercial applications of Opteon™ SF-10 as a heat transfer fluid include single-phase (non-phase-change) heat transfer fluids in semiconductor manufacturing, brine coolants, insulating liquids, fuel cells, reactor coolants, heat exchangers, dryers, turbines, heat pumps, and leak detection fluids for equipment (e.g., bubble testing). Its recommended operating temperature range is from −85 to 105 °C (−112 to 221 °F).
Advantages of Opteon™ SF-10
Low environmental impact: based on HFO technology, so its GWP is very low, much lower than commonly used PFCs, PFPEs, HFEs, HFCs and HCFCs;
Can be easily applied to existing equipment for seamless conversion, thereby reducing fluctuations in system operating conditions and shortening the certification process;
Excellent miscibility with other liquids, enabling drop-in replacement of other high-GWP liquids;
Low density: for the same charge weight, a larger volume is obtained at lower cost;
Low viscosity: reduces power consumption and operating costs;
Low dielectric loss constant, so it can be used for immersion cooling;
High safe exposure limit, good occupational safety.
Safety, Toxicity and Environmental Properties
Opteon™ SF-10 heat transfer fluid is a nonflammable liquid, and its thermal stability allows use up to 175 °C (347 °F). It has shown very good safety in mammalian studies. Its occupational exposure limit is 500 ppm. It is not irritating to skin or eyes. In environmental property tests, Opteon™ SF-10 is also safe for aquatic organisms.
