The addition of sTEpANpol polyester polyols enhances mechanical properties resulting in higher quality foams, less scrap, and easier fabrication. This allows for the manufacture of more durable furniture, and in turn, more satisfied customers.

fIlTraTIon

The small, regular foam cells produced by using sTEpANpol adipate polyols can filter air, fluids, and particulates in consumer, medical, and industrial applications.

auTomoTIve foamS

our patented chemistry increases the bonding strength of foam to textile and nonwoven fabrics. The increased adhesion enables better shaping and provides the cushioning, vibration and sound reduction properties essential for automotive headliners.

Typical end uses stepan supplies both aromatic and aliphatic polyester polyols for use in flexible slabstock polyurethane foam applications. sTEpANpol aromatic polyester polyols improve flame lamination bond strength and increase mechanical properties in polyether foams. our aliphatic polyester polyol product line contains branched adipate polyols designed for specialty polyester foams.
