Nanjing SiSiB Silicones Co., Ltd.
Nanjing SiSiB Silicones Co., Ltd.

With more than 30 years of manufacturing experience in silicone materials and polyurethane foam additives, SiSiB SILICONES provides specialty technologies for foam cell structure regulation and air flow control in flexible polyurethane foam systems.


SiSiB® Cell Openers are designed to regulate cell opening behavior and optimize air permeability in flexible foam applications. By modifying cell wall rupture behavior during foam formation, these products help achieve more uniform open-cell structures and controlled breathability.


Proper cell opening control is important for balancing softness, support performance, compression recovery, dimensional stability, and long-term comfort properties. The technologies are widely used in slabstock foam, high-resilience foam, slow-recovery foam, and specialty comfort foam systems.


Compared with general foam stabilizers, cell opener technologies focus more directly on foam openness, air flow regulation, and soft-touch performance.
