With more than 30 years of manufacturing experience in silicone materials and polyurethane additives, SiSiB SILICONES provides silicone surfactant technologies for polyurethane footwear foam applications requiring controlled processing behavior, durability, and surface quality.

SiSiB® Polyurethane Sole Foam Stabilizers are designed for shoe sole systems requiring balanced foam morphology, abrasion resistance, flexibility, and dimensional stability. These products help regulate cell structure, foam density distribution, and surface appearance during footwear foam production.

Depending on formulation and processing requirements, selected grades can improve resilience, demolding behavior, foam consistency, and finished surface quality in soft sole, semi-rigid sole, and specialty footwear systems.

Compared with conventional flexible foam stabilizers, footwear foam technologies place greater emphasis on wear resistance, processing reproducibility, and dimensional precision.
