STEPANPOL Aliphatic Polyester Polyols
STEPANPOL® aliphatic polyester polyols are built using a variety of acids and diols, in a broad range of molecular weights, enabling formulators to customize to desired properties. Stepan’s range of products also includes proprietary, innovative polyols to help achieve unmet needs in constantly changing markets.
• STEPANPOL® polyester polyols allow formulators the versatility in PUR hot melt adhesive applications to improve green strength, creep resistance, substrate bonding profiles and modify open time.
• STEPANPOL® polyester polyols deliver improved hydrolytic stability under acid and base conditions, flexibility, good pot life, and adhesion to a variety of commonly used substrates in flexible packaging adhesives.
• STEPANPOL® aliphatic polyesters contribute to excellent abrasion and tear resistance as well as providing strong load bearing in polyurethane elastomers and are commonly used in wheels, industrial and printing rolls as well as in mining equipment.
• STEPANPOL® polyester polyols can be further compounded to polyurethane prepolymers, radiation curable oligomers or polyurethane dispersions, offering hardness, flexibility, solvent resistance, and/or weatherability, depending on the grade.
