Stahl announced the global launch of PermUCell™, a next-generation, fully water-based coagulation technology designed to produce high-quality polyurethane (PU) substrates without using dimethylformamide (DMF). The new solution marks a major step toward more sustainable material production in industries such as performance footwear and synthetic materials. After gaining successful industrial adoption among manufacturing partners in Asia—the world’s largest hub for footwear and synthetic material production—the technology is now fully market-ready for global deployment.
Advancing DMF-Free Polyurethane Production
PermUCell™ offers manufacturers a practical pathway to meet growing sustainability requirements while maintaining product performance and production efficiency. Unlike traditional processes, the technology is completely DMF-free, helping producers significantly reduce environmental impact.
At the same time, the system integrates smoothly with existing coagulation production lines, allowing manufacturers to transition to cleaner technology without major infrastructure changes. As a result, companies can continue producing PU materials that meet the quality standards demanded by global footwear and fashion brands.
Importantly, PermUCell™ delivers enhanced product performance. Materials produced with the technology offer improved softness, breathability, and flexibility, creating a superior consumer experience while maintaining durability and aesthetic appeal.
Proven Performance through Industrial Implementation
Before its global launch, PermUCell™ underwent extensive industrial testing and implementation with manufacturing partners in both Asia and Europe. These large-scale trials demonstrated the technology’s reliability and readiness for commercial adoption. Consequently, Stahl is now rolling out the solution worldwide, enabling manufacturers to transition to sustainable PU production with confidence.
Global Technical Support for Seamless Adoption
To support customers during the transition, Stahl provides comprehensive technical assistance through its global network of specialists and application Centers of Excellence. These teams help manufacturers optimise production processes and ensure smooth integration of the new technology.
Key support services include:
*Production setup and parameter optimisation
*Integration with existing manufacturing lines
*Scaling up production capacity
*Material performance tuning to meet brand specifications
*Ongoing troubleshooting and process improvement
According to Montse Pous, the company aims to make the transition to cleaner technologies as seamless as possible. “Our goal is to enable a smooth and confident shift to sustainable coagulation technologies while maintaining stable process control and reliable technical performance,” she said.
Supporting the Industry’s Sustainability Transition
Stahl also emphasises that PermUCell™ supports the industry’s broader efforts to phase out harmful solvents such as DMF. By combining advanced technology with global technical support, manufacturers can accelerate their sustainability goals without compromising operational efficiency.
“As manufacturers move toward cleaner materials, PermUCell™ provides a proven pathway to eliminate DMF while maintaining product performance and production efficiency,” said Lidia Martinez. As per the press release, with the global rollout of PermUCell™, Stahl aims to help manufacturers across the footwear and synthetic materials industries adopt environmentally responsible production technologies while continuing to deliver high-performance polyurethane materials.
