ELEKTROVISKOSE FLUESSIGKEITEN

摘要

The invention concerns electroviscous liquids containing aluminium silicates with a water content of 1 to 25 % by wt. and esters, as well as a method of producing such electroviscous liquids. The invention also concerns the use of esters of polyols containing 2 to 6 hydroxy groups and 2 to 32 C-atoms, and monocarboxylic acids containing 2 to 32 C-atoms as an electrically non-conducting, hydrophobic liquid in electroviscous liquids. Such electroviscous liquids exhibit high electroreactivity, do not produce sediment, are compatible with work materials and, above all, are readily biodegradable.
