HS Number: 390799

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.

Polymer polyols – for exceptional firmness & stability

Boltorn™ H311 is a liquid polymer polyol that provides exceptional compressive loadbuilding 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 SANtype.

Compared to conventional technology, Boltorn™ H311 offers considerable benefits:

  • Two to three times the efficiency in providing compressive loads (IFD or CFD) at a given addition solids level, which allows lower average solids levels to be used
  • Exceptional firmness, extending beyond current state-of-the-art technology
  • Improved foam stability due to the cross-linking mechanism and reduced surface voids of finished parts
