ISO 6473 specifies the acronym for HS synthetics fluids, without further specifying their composition. Usually, these fluids are developed for specific applications. A typical example is the case of extreme temperature conditions. The technology for HS fluids is continuously evolving, and the number of options today available is too high to be summarized in a short list. Nevertheless, many current HS fluids are based on silicate esters and polyol esters.
