TERRIN™ 168

INVISTA’s TERRIN™ 168 polyol is a 100% aliphatic polyester polyol containing a minimum of 50% recycled content.(1) Due to its unique structure, TERRIN™ 168 polyol is an easily handled, lowviscosity liquid at room temperature and remains a pourable liquid at -15°C/5°F and below.(2) It does not crystallize, but exhibits Tg at approximately -75°C.

TERRIN™ 168 polyol can be used in lieu of or in combination with polyether or polyester polyols to formulate a variety of polyurethane products. The resulting polyurethanes can be designed to be soft and flexible - or hard and stiff.

Features and Benefits

  • Cost competitive in comparison to conventional polyols
  • 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
  • REACH and TSCA compliant

(1) As defined by ISO 14021, Section 7.8; preliminary estimate based on small-scale production. (2) Patents pending; Consult the MSDS for additional information
