Soft Polyurethane Foam Surfactant

Four primary functions of silicone surfactants in polyurethane foam production:
◆ Reducing the surface tension of raw materials to facilitate emulsification
◆ Assisting in the nucleation of dissolved gases within the system
◆ Providing stabilizing support to the foam. During foam growth, it prevents collapse and coalescence of bubbles, delays open-cell formation, and controls foam openness. At peak foam rise, it promotes phase separation of polyurea to achieve open-cell foam.

Whether a silicone surfactant meets these four fundamental requirements depends on its molecular structure and compatibility with specific polyurethane foam formulations. These four functions influence the final product's properties, such as density, breathability, density gradient, compression hardness, tensile strength, and resilience...
Therefore, the performance of a silicone surfactant depends on its suitability for the formulation system and processing conditions. To meet diverse formulation systems, performance requirements, and processing conditions, a range of different surfactants is needed. Accordingly, Chongyao Technology has developed a series of products to cater to the needs of the polyurethane foam industry:
