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

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.
