TERRIN™ polyols can be used in lieu of or in combination with conventional polyether or polyester polyols to formulate a variety of polyurethane products designed to be soft and flexible—or hard and stiff. These versatile, aliphatic, polyester polyols can be used in applications ranging from viscoelastic foam to spray coatings and adhesives to elastomeric resins.

Features and Specifications

  • Cost competitive in comparison to conventional polyols
  • Contain a minimum of 50% recycled content. TERRIN™ 170 polyol is made from raw materials that all either recycled or renewable(1)
  • All liquids with relatively low viscosities
  • Have similar hydroxyl values to castor oil, and can be substituted on a nearly equal weight basis
  • Supply of TERRIN™ polyols is not dependent on weather and planting cycles
