Boltorn™ H311

Boltorn™ H311 by Perstorp is dendritic polymer polyol with high hydroxyl functionality. It has highly branched flexible backbone with a large number of primary hydroxyl groups. It contains 10% water. It offers exceptionally high FD or CFD loads which could not be obtained normally with conventional flexible foam technology. It can increase foam stability and allows for high firmness at low density. Used to formulate foams with lower total solids levels due to its higher efficiency. Also used to replace copolymer polyols of styrene acrylonitrile (SAN) type or conventional type crosslinkers. Boltorn™ H311 is typically 2-3 times as efficient as SAN-type polymer polyols in providing compressive loads at given solids level.
