Momentive Introduces Niax* Silicone Y-16045 for Rigid Polyurethane Foam

    New Surfactant is an Excellent Candidate to Consider for Applications
Containing Low Compatibility or Low Solubility Blowing Agents

    WILTON, CONN., September 24 /CNW/ - Today, at UTECH North America
Exhibition & Conference, Momentive Performance Materials announced the
introduction of Niax(*) silicone surfactant Y-16045, a non-hydrolyzable silicone
copolymer that may be suitable for formulation into resin blends for the
manufacture of rigid polyurethane foams. Niax silicone surfactant Y-16045 is
an excellent candidate to consider for use in the manufacture of flexible
metal-faced laminated boardstock, rigid metal-faced boardstock and bunstock
blown with hydrocarbons due to its potential to substantially increase
emulsion stability when the resin components are blended into a system.

    "This new silicone surfactant is an excellent candidate for applications
containing low compatibility or low solubility blowing agents," said Alberto
Melle, global marketing manager, Momentive. "In addition to extended resin
emulsion duration, it can provide manufacturers of rigid polyurethane foam
with excellent foam stabilization and an extremely fine cell structure."

    The fine regular foam structure of foams typically produced with Niax
silicone surfactant Y-16045 results in low thermal conductivity performance.
The common usage level for Niax silicone surfactant Y-16045 ranges from 1.5 to
2.5 parts per hundred parts polyol.
