Polyester-polyols : C.A.S.E.

 

Stepan’s structure-property expertise and broad product line of aromatic and aliphatic polyester polyols for C.A.S.E. (coatings, adhesives, sealants and elastomers) provides formulators with the tools to bring innovative, quality products to the marketplace whatever the final application may be. STEPANPOL® products are available globally with local production in each region.

STEPANPOL® aromatic polyester polyols are specifically engineered to meet diverse and demanding requirements. By using phthalic anhydride as the building block, Stepan polyols deliver enhanced hydrolytic stability with an ortho-ester linkage and diverse substrate adhesion while improving abrasion resistance and overall hardness.

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.

Applications et utilisations typiques

Colles de fusion PUR

Les polyesters-polyols STEPANPOL® offrent aux formulateurs la polyvalence des applications de colles de fusion PUR pour améliorer la force d’adhérence, la résistance à la déformation, les profilés de liaison des substrats et modifier le temps ouvert.

FLEXIBLE PACKAGING ADHESIVES

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

Élastomères en polyuréthane

STEPANPOL® aliphatic polyesters contribute to excellent abrasion and tear resistance as well as providing strong load bearing thus are commonly used in wheels, industrial and printing rolls as well as in mining equipment.

URETHANE COATING RESINS

STEPANPOL® polyester polyols can be further compounded to radiation curable oligomers or polyurethane dispersions, offering hardness, flexibility, solvent resistance, and/or weatherability, depending on the grade.
