Zusammenfassung:Embodiments of the present disclosure are directed towards semi-flexible foam formulations that can be utilized to form semi-flexible foams. As an example, a semiflexible foam formulation can include a first polyether polyol having an average nominal hydroxyl functionality from 2 to 4 and a number average equivalent weight from 120 to 1500, a second polyether polyol having a having an average nominal hydroxyl functionality from 4 to 8 and a number average equivalent weight from 120 to 800, and a third polyether polyol having an average nominal hydroxyl functionality from 2 to 4 a number average equivalent weight from 200 to 500 and toluene diisocyanate.
