Used as a heat transfer fluid in electronic cooling systems due to its high thermal stability and low reactivity. Commonly found in immersion cooling setups for data centers and high-performance computing hardware. Acts as a dielectric fluid, allowing electronic components to be submerged directly without risk of damage. Also utilized in specialized industrial processes requiring inert, non-flammable liquids. Its low surface tension enables efficient wetting and coverage in cooling applications. Limited use in some medical devices and oxygen carriers in experimental settings due to its ability to dissolve gases. Environmental persistence has led to reduced use in consumer-facing products.
