Y-Warm functions as an ultra-thin thermal insulation layer within footwear, helping reduce heat transfer between the foot and the external environment while adding minimal thickness.

Manufacturing Method:
Y-Warm can be integrated as an interlayer between the shoe upper and inner materials using sewing or suitable lamination processes.

Independently tested by a third party commissioned by the client.

In a comparative footwear test, Y-Warm and a conventional footwear insulation material were evaluated using the same footwear construction.

At equivalent thermal insulation performance, the Y-Warm insulation layer required only approximately one-quarter of the thickness and weight of the conventional insulation material, demonstrating its potential for thinner, lighter insulated footwear.

Y-Warm can be integrated into different footwear constructions depending on the required levels of thermal insulation, weather protection, and cushioning.

2. Upper Material + Y-Warm + Fleece

3. Upper Material + Y-Warm + Foam + Lining

4. Upper Material + Waterproof Membrane + Y-Warm + Lining

5. Upper Material + Waterproof Membrane + Y-Warm + Foam + Lining

PUR lamination is the recommended method for bonding Y-Warm with compatible footwear materials, offering a mature and reliable solution for footwear construction.

Alternatively, low-temperature hot-melt adhesive web lamination can be used. This method requires precise control of temperature, pressure, and processing time to minimize the risk of damaging Y-Warm’s porous structure and affecting its thermal insulation performance.

Avoid simultaneous high heat and pressure, particularly above 100°C, as this may compress Y-Warm’s porous structure and reduce its recovery.

Higher temperatures and pressures increase the risk of structural deformation and performance loss.

Even a 50-meter roll of Y-Warm is lightweight enough to be easily lifted and handled with one hand.

In tested footwear applications, Y-Warm achieved equivalent thermal insulation performance with approximately one-quarter of the insulation material weight compared with conventional insulation.

Using less material for the same level of thermal performance can reduce insulation material consumption by approximately 75% by weight, supporting the development of lighter, more material-efficient footwear.
