SUNOIT™ Silicone PU Foam Stabilizers: Uniform Cells, Stable Foaming

Silicone polyurethane foam stabilizers are high-efficiency surface-active agents based on polyether-modified siloxanes, specifically engineered for PU foaming processes. By dramatically reducing system surface tension, they promote rapid emulsification and mixing of polyols and isocyanates while delivering excellent nucleation and foam stabilization. These products effectively regulate cell structure, optimize open/closed cell content, and prevent foam collapse and shrinkage, yielding fine, uniform internal structures and smooth surfaces. They are widely used in flexible slabstock, rigid insulation panels, integral skin, microcellular elastomers, and semi-rigid foams. SUNOIT offers a series of grades tailored to different foaming systems and densities, featuring broad formulation latitude and outstanding compatibility for box-foam, continuous, and molding processes. Backed by consistent quality and responsive technical support, SUNOIT delivers high-efficiency foam stabilization solutions that help customers achieve controlled cell structure and consistent physical properties in high-quality production.
