Momentive Introduces Niax* Surfactants for Microcellular Polyurethane Foam Applications

    Introduced at the UTECH North America Exhibition, New Niax Silicones
Typically Provide Superior Performance for Low-Density Foam

    WILTON, CONN., September 24 /CNW/ - Momentive Performance Materials today
announced an innovative family of Niax(*) silicone surfactants that may be
cost-effective for use in low-density foam formulations for important
applications such as footwear and automotive.

    Generally providing improved performance over the current industry
standard, Niax silicones L-1501, L-1502, L-1503 and L-1504 are "cell
regulators" that may be highly useful in a variety of polyurethane systems and
across a wide range of microcellular foam densities. Niax silicones L-1505,
L-1506 and L-1609 are "shear stabilizers" to be considered for use with the
Niax cell regulators in ester, ether or mixed ester/ether systems.

    "This new family of Niax silicones provides manufacturers with the best
of both worlds - options for outstanding value and high performance," said
Alberto Melle, global marketing manager, Momentive. "Through the use of our
new line of surfactants, in conjunction with our new generation cell-opening
Niax catalysts, customers may achieve outstanding end product performance
without sacrificing cost efficiencies."

    Cell regulating Niax silicone L-1501 typically helps provide the broadest
use level latitude and allows the greatest cell opening. Niax silicone L-1502
may help improve skin formation. Niax silicone L-1504 may be a more
cost-effective surfactant alternative within a narrower use range. Niax
silicone L-1503 is an excellent candidate to consider as a potential
cost-effective alternative for automotive applications where reduced silicone
fugitivity is a requirement.

    Below a foam density of 0.32 g/cc the cell-regulating surfactants tend to
work synergistically with Momentive's shear-stabilizing surfactants. Shear
stabilizers Niax silicone L-1505 (high performance for ester-based systems),
Niax silicone L-1506 (cost-effective for both ester and ether-based system)
and Niax silicone L-1609 (high performance for ether-based systems) typically
reduce cell collapse and improve surface skin formation in the end product
