3m Fluorinert FC-40
BP=165?C
3M氟化液FC-40是无色透明全氟化学品，具有良好的化学惰性、电气绝缘性能、热传导性和独特的第表面张力广泛应用于半导体制造厂作为热传导介质。其液体温度范围为-57°C 至 155°C，主要应用于蚀刻设备、离子注入设备、测试设备及其他设备。因为FC-40是单一组分，所以其成分不好出现降解或者过期。FC-40沸点高，其随时间的挥发也比较少。
MILITARY STANDARD TESTING FLUID
The high dielectric strength and wide liquid range of Fluorinert liquid FC-40 allows its use in a variety of testing applications, including electronic reliability and hermetic seal/gross leak, and thermal shock testing. Hermetic seal/gross leak testing generally follows Military Standards 883-1014, 750-1071 and 202-112; FC-72 liquid conforms to these specifications.
HEAT TRANSFER FLUID
With a pour point of -57°C and excellent low temperature viscosity, Fluorinert liquid FC-40 is an ideal fluid for use in medium temperature heat transfer applications. Its high dielectric constant also means that it will not damage electronic equipment in the event of a leak or other failure.
Fluorinert Liquids are a family of clear, colorless, odorless perfluorinated fluids having a viscosity similar to water. These non-flammable liquids have set the standard in the electronics industry for over 40 years, meeting the demanding and diverse requirements of many heat transfer, manufacturing and testing applications.
Fluorinert liquids are thermally and chemically stable, compatible with most sensitive materials, including metals, plastics and elastomers, and are practically non-toxic through normal routes of industrial exposure.
Fluorinert liquids are completely fluorinated, containing no chlorine or hydrogen atoms. The strength of the carbon-fluorine bond contributes to their extreme stability and inertness. This chemical structure also results in very low intermolecular forces, low surface tension and essentially no solvent action on non- fluorinated compounds.
The dielectric strength of perfluorinated liquids is high—in excess of 35,000 volts across a 0.1 inch gap. Water solubility is on the order of a few parts per million. The nominal boiling point of each fluid in this series is determined during their manufacture. Fluorinert liquids are available with boiling points ranging from 30?C to 215?C and pour points as low as -127?C.
