Features Of SilGuard YK-1211 Polyurethane Surfactant

  1. Optimized silicone-polyether copolymer structure for superior foam stabilization in flexible polyurethane systems.

  2. Low surface tension and excellent migration resistance, minimizing surface defects and craters.

  3. High hydrolytic stability ensures consistent performance during storage and processing.

  4. Compatible with conventional amine and tin catalysts, as well as common polyol and isocyanate blends.

  5. Non-VOC compliant formulation supporting low-emission foam production requirements.

Typical Applications Of SilGuard YK-1211 Polyurethane Surfactant

  1. Flexible slabstock polyurethane foam for bedding and furniture.

  2. High-resilience (HR) molded foam used in automotive seating.

  3. Integral skin foams for steering wheels, armrests, and dash components.

  4. Water-blown and low-pressure foam systems requiring fine cell structure control.

  5. Fire-retardant foam formulations where surfactant compatibility with FR additives is critical.
