“Gist”: Use of ester plasticizers in flexible foams

Why it is interesting: According to this invention both the humid aged compression set and the hand ‘feel’ of flexible foams can be improved by incorporating a few percent of a mono- di- tri- or tetra- ester plasticizer in the polyol. In the examples 1 to 4 php of isopropyl myristate does indeed seem to improve the humid aged compression set of an MDI-TDI foam, however not all examples are very convincing.
