Product Information
TMC-7000 Engineered Fluid is a miscible drop in replacement for 3M Novec 7000.
TMC-7000 is a clear, colorless, thermal stable dielectric fluid capable of extreme low temperature operation (-120C). The properties of TMC-7000 make it very useful in a variety of heat transfer applications in the semiconductor, electronics, chemical manufacturing industries. It is also non-ozone depleting and has very low global warming potential making it an attractive alternative to perfluorocarbon and perfluoropolyether heat transfer liquids.
MATERIALS COMPATIBLITY
TMC-7000 is compatible with metals, glasses, ceramics and polymers. Material compatibility testing for “soft” or elastomeric polymers in TMC-7000 is primarily focused on two effects: the extraction of mobile organics such as plasticizers from the polymer and the absorption of the fluid into the polymer. The former is associated with hardening or shrinking of the polymer and the latter with swelling and softening of the polymer or diffusion of the fluid through it. TMC-7000 is unlikely to swell common hydrocarbon elastomers such as EP, EPDM, nitrile and butyl.
Other materials, such as highly fluorinated or silicone elastomers, are prone to absorption and swelling. Material compatibility testing can be used to quantify these effects. This testing reveals significant variation in the extractable content of elastomers within any elastomer category. Application experience reveals that not all applications are equally sensitive to dimensional and hardness changes. For these reasons, material compatibility should be treated on a case-by-case basis at the discretion of the system designer with the specific application in mind.
