High Mw Polyols for PU and STP Polymers


Polyether polyols are key components used in the production of polyurethanes. AGC produces polyether polyol (PREMINOL™) from Propylene Oxide. These polymers, available in the Americas, have high molecular weights exceeding 10,000. AGC employs an advanced catalyst process which results in polyols with ultra-low monol content, and a narrow molecular weight distribution.


PREMINOL™  Properties

PREMINOL has ultra-low monol content, high molecular weight ranging from 4,000-42,000, and a narrow molecular weight distribution. This provides good mechanical properties, high flexibility, good durability and good workability for coatings, adhesives, sealants, and elastomer applications.

(High Molecular Weight for Coatings, Adhesives, Sealants and Elastomers)

  • Ultra-low monol content
    • Good mechanical properties
    • Fast curing
  • High molecular weight
    • High flexibility
    • Good durability
  • Narrow molecular weight distribution
    • Good workability

(High Molecular Weight for Coatings, Adhesives, Sealants and Elastomers)

  • Good mechanical properties
    • High flexibility and high cohesive force are suitable for elastic adhesive
  • Good durability
    • High mechanical strength and high elongation enable to provide high durability sealants
  • Good workability
    • Low viscosity of formulation enables to seal easily even at low temperatures
  • Fast curing
    • Fast cure enables to shorten the total process time
  •  Environmentally friendly (Plasticizer free, Solvent free)
    • High flexibility and low viscosity polymer enable to reduce the amount of plasticizer and solvent in the formulation

Can be applied to a wide variety of curable polymers by modifying the hydroxyl groups:
