Y-Warm is an ultra-thin, lightweight thermal insulation material engineered to deliver high thermal efficiency with minimal thickness.
At just 0.7 mm, a single layer can provide a perceived warmth increase of approximately 10°C under specified test conditions, while reducing reliance on the thickness and bulk traditionally associated with thermal insulation.
With an operating temperature range of −50°C to 150°C, the material provides effective thermal insulation across apparel, footwear, outdoor gear, and a wide range of industrial applications.
Engineered with hydrophilic functionality, Y-Warm effectively absorbs and manages moisture while maintaining its thermal insulation performance.
According to GB/T 21655.1-2023, the material achieved a water absorption rate of 280% before washing and 279% after washing, demonstrating high and durable absorption performance.
In apparel and footwear applications, this capability helps reduce moisture accumulation on the body-facing side and support comfort during wear.
Y-Warm combines high moisture absorption with rapid drying.
In comparative testing, the material reached a dry state in approximately 60 minutes, despite absorbing more moisture than the comparison fabrics.
Combined with ultra-thin, lightweight thermal insulation, this quick-drying capability helps reduce moisture accumulation and support comfort during extended wear.

Technical Overview
At the heart of Y-Warm is a closed-cell system of micron-scale cells defined by nanoscale polymer walls.
By controlling heat transfer at the microscale, this honeycomb-like design enables extremely low thermal conductivity comparable to that of aerogel.
This marks a shift in thermal insulation technology — from relying on material loft to engineering thermal performance through microstructure.

Laminated Products
For thousands of years, warmth has largely depended on one principle: trapping still air with thickness and loft.
From grasses, leaves, and natural fibers to fur, down, and modern synthetic insulation, materials have evolved — but the fundamental approach has remained largely unchanged.
Y-Warm takes a different approach.
By engineering thermal insulation at the microstructural level, high thermal efficiency is achieved in an ultra-thin, lightweight form, reducing the traditional reliance on bulky, loft-based insulation.
From adding more material to engineering better structure.
This shift represents a new direction in thermal insulation technology — and a step forward in the evolution of advanced thermal materials.
