Silicone Surfactants B8681 is a phthalate‑free polyether‑modified polydimethylsiloxane surfactant engineered for flexible & high‑resilience (HR) polyurethane (PU) foam systems. It delivers balanced cell nucleation, stable foaming, uniform cell structure, and optimized foam openness (crushability). With low VOC, low emission, and wide processing compatibility, it is highly versatile for TDI 80–based formulations and widely used in high‑quality flexible foam production.
