Stepan’s expertise and broad product line of aromatic and aliphatic polyester polyols enable you to bring quality products to the marketplace more efficiently, whatever your final application may be.
STEPANPOL® aromatic polyester polyols are specifically engineered to meet the diverse and demanding requirements of the C.A.S.E. (coatings, adhesives, sealants and elastomers) industries. Stepan has developed a line of high quality polyester polyols that are based on ortho-ester linkages. By using phthalic anhydride as the building block, Stepan polyols deliver enhanced hydrolytic stability and diverse substrate adhesion while improving abrasion resistance and overall hardness.
Aliphatic polyester polyols are built using various acids and diols, enabling you to customize the desired properties of your various offerings.
Typical End Uses
PUR hot-melt adhesives
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. Applications include fabric laminating, woodworking and product assembly.
STEPANPOL® delivers superior hydrolytic stability under acid and base conditions, flexibility, good pot life and adhesion to a variety of commonly used substrates.
One-component foam (OCF) formulators choose STEPANOL® aromatic polyester polyols for in-can stability, fire retardancy, adhesion to a variety of substrates and cost-effectiveness.
