Boltorn™ H311

Boltorn™ H311 by Perstorp is a dendritic polymer polyol with high hydroxyl functionality. It is a viscous liquid at room temperature. It has excellent solubility in polyether polyols, glycols and polyalcohols. It increases foam stability and allows high firmness at low density. It is an effective load builder for high firmness molded foam and high resilience (HR) slabstock foam. It can provide exceptionally high FD or CFD loads, normally not achievable with conventional flexible foam technology. It offers high efficiency in foam formulations with lower total solid levels. Boltorn™ H31 can be used to replace copolymer polyols of styrene acrylonitrile (SAN) type or conventional type crosslinkers. It is 2-3 times as efficient as SAN-type polymer polyols in providing compressive loads at given solids level.
