Looking for a real change in PUR and PIR insulation foam?

New Resonance™ Aromatic Polyols - Building Blocks for the Polyurethane Industry

5 Good Reasons for a Change

  • Enhance thermal insulation
  • Best in class reaction to fire
  • Improve mechanical properties
  • Greater dimensional stability
  • Increase productivity and improve panel geometry

Bakelite Polyols

A superior building block for PUR and PIR

Polyol portfolio

Our aromatic polyol portfolio will help you address regulatory needs today and tomorrow while meeting processing and performance requirements for your PUR and PIR formulations. With a range of functionality, aromaticity and hydroxyl Values, they can be used as building blocks for demanding formulations or as building blocks toward other resins.

Bakelite’s novel Resonance™ polyols serve as building blocks for PUR and PIR formulators by combining the green strength and mechanical properties of polyether polyols with the resistance to fire of aromatic polyester polyols. This can translate into improved reaction to fire, thermal insulation performance, dimensional stability and mechanical strength.

Features of Resonance™ polyols include:

  • 25 to 78% aromaticity
  • Functionalities of 2.6 to 6.0
  • Hydroxyl values of 175 to 550
  • Viscosities to meet the needs of most applications
  • Drum to bulk packaging

Resonance™ Auto-Catalytic Aromatic Polyols

Whether as an additive or as a co-polyol, our auto-catalytic aromatic polyether portfolio will help you address reaction to fire related regulatory actions for PU rigid or flexible foam systems. The polyols can be used as a melamine alternative for PU flexible foam, as additives in rigid foam for improved reaction to fire, or to minimize the need for aliphatic polyols or fire retardants in CASE and foam systems.

Resonance™ Aromatic Polyols

At minimal levels, Resonance™ aromatic polyols have been used in the PU industry for decades. Suggested uses are for adhesives, cast elastomers, and discontinuous foam processes. The high aromaticity, >75%, provide good reaction to fire while the functionality and hydroxyl values improve polymer modulus, foam productivity, and aged lambda. The phenolic hydroxyl group exhibit a foam insulation maximum temperature increase that are similar to secondary hydroxyls without harming reaction to fire.

Resonance™ Aromatic Polyether Polyols

As co-polyol or as the sole polyol, several of our aromatic polyether polyols have been qualified in 2K adhesives, cast elastomers, and several rigid foam formulations. The polyols can be used to reduce the aliphatic polyether polyol for improved reaction to fire or to reduce the aromatic polyester polyol to adjust system functionality, aromaticity, and hydroxyl value, and therefore improve mechanical properties. All of the aromatic polyether polyols are compatible with the new generation of hydrofluoroolefin blowing agents.
