It represents an unparalleled technological advancement in shoe insulator.

Manufacturing Method:

It is used as an interlayer, sandwiched between the shoe upper and other materials through lamination or sewing.

Independently certified by a client-hired third party:

Y-Warm and renowned materials were both applied in the same footwear for a performance comparison. Y-Warm footwear, at just 1/4 the weight and thickness of those made with notable materials, delivers equivalent insulation, confirming its performance as a lightweight insulation material.

PUR is an advanced and mature lamination process, serving as the optimal solution for laminating Y-Warm with other shoe materials. 

Alternatively, low-temperature hot-melt adhesive "web" flat lamination is an option, but it demands advanced lamination skills and strict management. Otherwise, the porous structure of Y-Warm may be damaged.

Hot pressing above 100°C flattens Y-Warm holes, which cannot fully rebound.

Higher temperature and pressure exacerbate hole damage.

Using the same petrochemical raw materials, Y-Warm achieves equivalent performance with only 1/4 of the weight.

By reducing resource consumption by 75%, it has become the most sustainable thermal insulation material for footwear.
