NUCLEOOS

CO2 foaming technology for ultra-lightweight polyurethane soles

The NUCLEOOS CO₂ foaming technology is designed specifically for ultra-lightweight polyurethane soles. It combines the physical action of CO₂ (or nitrogen) with the chemical reaction of polyurethane to create a low-density foam that still maintains strong mechanical properties. This makes it ideal for footwear applications where comfort, durability, and reduced weight are critical.

In short, this technology allows manufacturers to cut material use nearly in half while still producing soles that are strong, flexible, and lightweight. It’s a clever balance of sustainability and performance that footwear brands can leverage to reduce costs and environmental impact.
