Rethinking Warmth: Thin, Light, and Highly Efficient
Y-Warm is the first nano closed-cell flexible insulation of its kind. Just 1 millimeter thick, the material packs more than 10,000 microscopic air pockets per square centimeter, effectively limiting heat transfer while maintaining moisture-permeability, quick-drying capability, and antibacterial performance. In practical use, Y-Warm delivers the same level of insulation as conventional materials at only a quarter of the weight and thickness. It performs reliably across extreme temperatures ranging from -50°C to 150°C. Compared to standard materials, it absorbs twice as much moisture, dries 2.5 times faster, and achieves top-tier (5A) antibacterial performance.
The technology is the result of eight years of R&D, overcoming a long-standing challenge in materials science: how to make nanoporous materials flexible instead of brittle. The outcome is a fabric-like insulation that combines durability with high performance. With Y-Warm, new possibilities for cold-weather products are unfolding.
A Smarter Approach to Sustainability
People have long resigned themselves to bulky winter footwear, accepting thick layers as necessary for warmth, even at the cost of added weight and higher resource consumption. Y-Warm takes a different approach. It delivers better thermal performance with less material.
This is when the “reduce” principle comes in. Y-Warm can cut raw material use by up to 75% without compromising performance. It also meets strict safety standards. The material complies with EU SVHC safety standards covering 249 substances, and contains no PFAS or toxic substances. As the industry shifts toward greener manufacturing, Y-Warm offers a cleaner, more sustainable solution.
Today, Y-Warm is already used across more than 20 sectors, including apparel, footwear, outdoor gear, automotive interiors, high-speed rail, and aviation.
