A zero heat flux occurs when there is no temperature difference between seat and occupant: this transition point is known as the heat flux inversion point
. When using heat flux mapping for evaluating effectiveness of climate seat technology in warm environments, one of the key metrics is to determine how quickly a hot soaked seat transitions from heating the occupant to removing heat from the occupant.
Phase inversion point
in accord to Jordhamo law would be in PP-rich area because the PP/EVOH viscosity ratio is obviously below one.
Defenders of inversion point
out that it's perfectly legal, quite a lot of work to achieve, and increasingly popular because U.S.
Phase Inversion Point
. It is important to introduce the phase inversion point
The critical volume fraction of the dispersed phase to which the inversion occurs is the phase inversion point

" Colloid & Polymer Sci.
Only one layer, totally mixed, is then present: this is the inversion point
. With a further increase of liquid velocity, the proportion of species lL continues to increase in the bottom mixed layer until the last particle of species hS from the lower layer enters the upper pure layer to form a clean-cut segregation between the two species, but with the layers reversed at this very high velocity compared to the first clean-cut segregation pattern at very low velocity.
If the oven operating temperature coincides with the inversion point
of the quartz, and the inversion point
is higher than the permissible ambient temperature, the influence of the external temperature on the oscillator and, in particular, the quartz is minimized.
In this work, we have formulated binary blends of PA6, 10 and PTT over the full compositional range with the goal of locating the approximate phase inversion point
, assessing the degree of cocontinuity in this region, and differentiating the domains of the component polymers by energy dispersive spectroscopy (EDS).
The results clearly indicated that the critical volume fraction of dispersed (or organic) phase where inversion appears (phase inversion point
) varies with system and is affected by a number of physical and operational parameters, such as liquids' properties, container geometry and initial conditions.

The phase continuity and phase inversion point
of the blends can be calculated theoretically using various expressions.
