Polyether polyol compositions

A polyether polyol composition comprising:

• a first polyether polyol having an average nominal hydroxyl functionality from 2 to 4 and a number average equivalent weight from 120 to 1500, wherein the first polyether polyol includes a polymer chain having from 0 weight percent to 15 weight percent of constitutional units derived from ethylene oxide and 85 weight percent to 100 weight percent of constitutional units derived from propylene oxide;
• a second polyether polyol having a having an average nominal hydroxyl functionality of 4.7 and a number average equivalent weight from 120 to 800, wherein the second polyether polyol includes a polypropylene oxide polymer chain and the second polyether polyol is formed with only one alkylene oxide, wherein the one alkylene oxide is propylene oxide;
• and
• a third polyether polyol having an average nominal hydroxyl functionality from 2 to 4 a number average equivalent weight from 200 to 500, wherein the third polyether polyol includes a polymer chain having from 30 weight percent to 85 weight percent of constitutional units derived from ethylene oxide and 15 weight percent to 70 weight percent of constitutional units derived from propylene oxide;
