Description:
Polyurethane surfactants are utilized across a broad range of polyurethane applications including footwear, mattresses foams, automotive interiors, and foam insulation used in refrigerators and construction. The function of a surfactant can be to enhance chemical compatibility of isocyanates and polyols, improve cell nucleation and stabilization and to prevent coalescence. Surfactants work by preserving the thermodynamically unstable state of a foam while it is rising by affecting surface forces until the polyurethane polymerizes far enough to maintain the cell structure. This webinar is intended to give a fundamental overview of how polyurethane surfactants work.
