Polyester-Polyols

Polyester polyols for flexible and rigid polyurethane (PU) systems

NiMAC provides high-performance, partially bio-based polyester polyols ideal for the formulation of flexible and rigid polyurethane (PU) systems. These low-molecular-weight polymers feature terminal hydroxyl groups and outperform polyethers in thermal and flame resistance while supporting sustainability goals.

Applications of PU Polyester-Polyols

Due to their performance and biodegradability, our polyester polyols are used in a wide range of PU and TPU applications:

  • Flexible and rigid foams
  • PU coatings and adhesives
  • Sealants and elastomers
  • Synthetic leather and textiles
