Resonance™ Polyols for Polyurethane and Polyisocyanurate Foams

Foam producers who want to enhance reaction to fire and smoke density of their products while improving productivity now have an attractive alternative to traditional technologies.

Hexion’s novel Resonance™ polyols combine the best properties of polyester and polyether polyols. Offerings include products with a range of nitrogen content that are self-catalytic and non-volatile. Benefits include:

  • Best-in-class reaction to fire
  • Opportunity to reduce overall system costs by decreasing catalysts and fire retardant additives
  • Potential for higher line speed and better panel planarity due to lower post-expansion
  • Finer cell structures that offers potential to improve thermal insulation

Resonance polyols are being used as “drop-in” replacements for both polyester and polyether polyols in commercial grade polyurethane and polyisocyanurate foams. Hexion offers a range of Resonance polyol options for panel, appliance and spray applications.
