HIPRE

HIPRE is the abbreviation for high internal phase ratio emulsion . These are highly concentrated emulsions , i.e. the discontinuous, dispersed phase is characterized by volume fractions of more than approx. 70%.

Compared to conventional emulsions, HIPREs are characterized by fundamental differences in viscosity behavior and structure. The individual domains of the dispersed phase take on a polyhedral shape with a volume fraction of more than approximately 74% .

Among other things, the terms biliquid foams or polyaphrons are also used in scientific circles .
