STEPANPOL® AA-58 is an aliphatic polyester polyol. I can be used in formulation polyurethanes for polyester flexible slabstock foams, elastomers, and sealants with a fine cell size at lower viscosity.
STEPANPOL® PC-2019-55 is a solvent-free saturated polyester polyol. it can be used to make polyurethans which may exhibit exceptional hydrolysis resistance, and combine a balance of mechanical strength with resilience.
STEPANPOL® PC 5130-160 is a solvent free, branched polyester-ether polyol. It can be used alone or in combination with other polyester polyols to form tough, flexible and water resistant polymers when cross-linked with polymeric MDI. In addition, it can be used to formulate 2-K coatings, concrete and sports flooring, primers and adhesives.
STEPANPOL® PC 5220-160 is a liquid amorphous, saturated, aliphatic slightly branched polyester polyol. This product can be used in formulation urethane coatings, adhesives, sealants, and elastomers and exhibits hydrolysis resistance and very good thermal stability.
Mainly used in PURHM adhesives, UV-cure and PUD’s. Excellent hydrolysis, thermal stability and bonding. Shortens open time in PURHM adhesives.
STEPANPOL® PDP 70 is a diethylene glycol-phthalic anhydride-based modified polyester polyol that can be used in formulationg urethane CASE products.
Provides excellent hydrolysis resistance, thermal stability and bonding in PURHM adhesives, UV-cure and PUD’s. Lengthens open time in PURHM adhesives. Adhesion promoter for metals and plastics.
Excellent green strength improver and extends open time in PURHM adhesives and UV-cure systems. Provides great hydrolysis resistance.
Excellent general purpose low viscosity polyester polyol. Used in adhesives, OCF and polyurethane foams.
STEPANPOL® T327 is a branched medium aromaticity modified polyester polyol. It can be used for production of rigid polyurethane PUR for continuous and discontinuous lamination (water blown) spray, moulding, and adhesives.
STEPANPOL® T401 is a modified aromatic polyester polyol. It can be used for the production of one component foams and polyisocyanurate foams.
