CO2 foaming technology for ultra-lightweight
polyurethane soles

The physical action of CO₂ or nitrogen, combined with the chemical reaction of polyurethane, generates a low-density foam with outstanding physical-mechanical properties and low weight.

A plug-and-play technology ready for production

NUCLEOOS takes shape in an advanced processing unit, designed to be integrated into STEMMA direct-injection, pouring and spraying systems, without affecting the production process.

Advanced solutions for high-performance applications

Compatible with both polyester- and polyether-based polyurethane systems, NUCLEOOS stands out for its exceptional application flexibility.

Dedicated formulations are also available, developed and marketed by leading polyurethane manufacturers for specific applications where lightness and low density are combined with high physical and mechanical performance.

Sustainability and Efficiency

CO₂ is one of the most sustainable and safest blowing agents available.

Naturally non-flammable and non-toxic at low concentrations, it ensures high safety standards and reliable management in the most advanced industrial processes.

With NUCLEOOS technology, these advantages result in tangible benefits: a reduction in polyurethane consumption of up to 45%, with a direct impact on production efficiency and a significant reduction in environmental footprint.
