Y-Warm to Showcase Next-Generation Thermal Material at the 27th Jinjiang Footwear International Expo

The four-day event is expected to span more than 60,000 square meters and attract over 150,000 professional visitors from China and abroad. The expo will feature themed zones covering smart sports equipment, sports technology, advanced materials, and footwear and apparel innovation, highlighting the growing integration of artificial intelligence, the Internet of Things, and new materials across the footwear and sports industries.

Beijing Y-Warm Technologies Co., Ltd. will participate in the exhibition's footwear materials section, presenting the latest iteration of its Y-Warm super-performance thermal insulation material, according to the company.

"Platforms like the Jinjiang Expo play a critical role in connecting material innovation with real-world industrial applications," said Zhong Feipeng, Chief Scientist of Beijing Y-Warm Technologies.

Advances in Flexible Thermal Insulation

Y-Warm is a flexible, nano closed-cell thermal insulation material developed by Beijing Y-Warm Technologies. At the upcoming expo, the company will introduce its nitrogen-supported closed-cell structure, a technology that enables high thermal efficiency within an ultra-thin profile.

According to the company, a 1-millimeter-thick Y-Warm layer contains more than 10,000 independent micrometer-scale closed cells per square centimeter, achieving thermal insulation performance comparable to aerogel while maintaining flexibility. The company says, in comparison with conventional insulation materials, the material offers three key advantages:

• Thermal conductivity as the primary performance metric instead of trapped air volume;
• Thermal insulation with moisture permeability and quick-drying performance;
• Lightweight construction that reduces bulk, particularly for children's footwear, where excessive thickness can affect gait development.

Y-Warm represents a shift from traditional "passive warmth" toward active thermal insulation, the company said. The material's hydrophilic molecular structure allows moisture generated during physical activity to be absorbed and released efficiently, helping balance warmth and breathability-an ongoing challenge in winter sportswear.
