Redefining Thermal Insulation
Just 0.7 mm. Approximately +10°C Warmer
Y-Warm is a new-generation thermal insulation material that delivers highly effective insulation in an ultra-thin form.
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.
Moisture Management
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.
Quick-Drying Performance
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 core of Y-Warm technology is a “flexible” structure of micrometer-sized closed cells formed by nanometer-thick polymer cell walls.
In material 1 mm thick, each square centimeter contains more than 10,000 individual micrometer-sized closed cells. By controlling heat transfer at the microscopic scale, this honeycomb-like structure exhibits extremely low thermal conductivity comparable to that of aerogels.
This represents a shift in the approach to thermal insulation—from relying on material loft to achieving highly effective insulation through microstructural design.

Precautions
Apparel Products
1.Avoid applying pressure at temperatures above 100°C, as this may impair pore recovery.
2.Avoid dense quilting, as it may increase material stiffness and affect garment hand feel.
Laminated Products
1. Avoid applying pressure at temperatures above 100°C, as this may impair pore recovery; higher temperatures and pressures may cause greater performance degradation.
2. Avoid full-coverage adhesive lamination, as it may significantly reduce moisture vapor permeability.
Selected Brands Using Y-Warm
The Transformative Power of Technology
For thousands of years, warmth has largely depended on one principle: using loft to trap air and limit its movement.
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, Y-Warm achieves high thermal efficiency in an ultra-thin, lightweight form, thereby reducing reliance on traditional loft-based insulation materials.
From adding more material to engineering more efficient structures.
This shift represents a new direction in thermal insulation technology — and a step forward in the evolution of advanced thermal materials.
