Boltorn™ H311

Boltorn™ H311

Boltorn™ H311 is a dendritic polymer polyol with more than 20 terminal hydroxyl groups and a highly branched flexible backbone. This liquid polymer polyol provides exceptional compressive load-building characteristics in flexible foam at very low addition levels. It is used as an additive, partially replacing conventional cross-linkers or graft co-polymer polyols of SAN type. Contains 10 % water and is a viscous liquid at room temperature.

Key Attributes
  • Boltorn™ H311 is a dendritic polymer polyol with high hydroxyl functionality.
  • Highly branched flexible backbone with a large number of primary hydroxyl groups.
  • Contains 10 % water and is a viscous liquid at room temperature.
  • Excellent solubility in polyether polyols, glycols and polyalcohols.
Product Highlights
  • Typically 2-3 times as efficient as SAN-type polymer polyols in providing compressive loads at given solids level.
  • Higher efficiency of Boltorn results in foam formulations with lower total solids levels.
  • Can provide exceptionally high FD or CFD loads, normally not obtainable with conventional flexible foam technology.
  • Increases foam stability and allows for high firmness at low density.

Applications & Uses

+
Recommended Uses & Known Applications
  • Boltorn™ H311 is an effective load builder for High Firmness moulded foam and High Resilience (HR) slabstock foam.
  • Can be used to replace copolymer polyols of styrene acrylonitrile (SAN) type or conventional type crosslinkers.
