Stahl Launches Sustainable Embossable Polyurethane Solution for Synthetic Leather

Stahl, a global leader in speciality coatings for flexible materials, has unveiled PermaQure® EPU, a long-lasting embossable polyurethane (EPU) solution designed to enhance synthetic leather and PU-coated textiles across fashion, upholstery, footwear and more. Showcased at K 2025, the innovation builds on Stahl’s PermaQure® high-solids PU platform to deliver a robust embossing window and durable grain quality, ensuring seamless compatibility with existing PVC embossing lines.

Addressing growing regulatory and customer demand for PVC alternatives, the chlorine-free EPU offers a more sustainable option without compromising on performance. As the first embossable 100% solids PU resin, PermaQure® EPU marks a breakthrough in synthetic leather production by allowing coatings to be applied on flat paper followed by post-embossing, significantly reducing costs and enabling greater design flexibility.

This efficient process eliminates reliance on pre-embossed paper, expanding creative possibilities and improving protection of unique textures. The EPU’s high solids content improves grain definition and retention over time, delivering superior aesthetic and functional performance. Beyond its technical advantages, the solution reinforces Stahl’s commitment to sustainable innovation, offering manufacturers a versatile, environmentally responsible alternative to PVC. With PermaQure® EPU, Stahl strengthens its leadership in next-generation surface solutions, combining durability, design freedom and reduced environmental impact for the global synthetic materials industry.
