Microcellular Polyurethane Foams
Microcellular polyurethane foams are the material of choice for a wide range of applications including footwear, sports material, and integral skin products that demand an essential balance of durability, comfort and excellent surface finish.
Achieving these properties depends on specialized additives that control cell structure, support mechanical integrity and ensure smooth, defect-free, high-quality polyurethane surfaces.
Additive Technologies for Microcellular and Integral Skin PU Foams
We offer a broad portfolio of catalysts, surfactants, performance additives, and release agents for microcellular polyurethane foams used in footwear, integral skin applications, and other molded parts. Achieving the right balance of comfort, durability and surface quality depends on additives that precisely control cell structure, foam density and surface formation.

Additive Solutions for Modern Footwear
Integral skin foams used in footwear require precise additive control to achieve uniform skin formation and a durable, flexible core. Footwear materials must deliver performance, comfort, durability, and visual appeal. Polyurethane remains a material of choice to meet these demands. Evonik's microcellular and integral skin foam additives provide consistent processing, helping you optimize cell structure, improve long-term cushioning, reduce surface defects, and meet both emission and performance requirements.
- Our TEGOSTAB® surfactants stabilize foam structure across a wide range of densities.
- DABCO® catalysts improve flow, support controlled reactivity and help to shorten demolding times.
- ORTEGOL® performance additives help meet tough industry standards by delivering abrasion resistance, antistatic protection, and better adhesion.
- GORAPUR® release agents enable easy demolding while allowing customization of surface appearance and texture.
Additive Solutions for Microcellular Foam and Integral Skin Applications
Selecting the right combination of additives is crucial for high-quality microcellular and integral skin PU foams. Our additives stabilize cell growth, support uniform skin formation and help prevent shrinkage and surface collapse. The result is not only improved quality of molded polyurethane parts but also more flexible production, fewer scrap issues and lower emissions.
Evonik provides additive solutions for a wide range of applications from automotive and furniture to safety gear or sports equipment: DABCO® and POLYCAT® catalysts help increase productivity. TEGOSTAB® surfactants promote smooth skin formation and better compatibility with diverse raw materials. ORTEGOL® performance additives improve abrasion resistance and adhesion, while GORAPUR® release agents deliver clean demolding and the desired surface finish. In combination, these products help molded microcellular parts meet both aesthetic and mechanical performance objectives.
