Y-Warm is manufactured using a water-based process in place of organic solvents such as toluene, DMF, and ketones, reducing reliance on organic solvents in production.

Independent SGS testing found the tested Substances of Very High Concern (SVHCs) to be below the applicable reporting limits, supporting compliance with relevant EU REACH requirements.

In footwear comparison tests, the Y-Warm insulation layer weighed approximately 75% less than the tested conventional insulation layer while providing comparable thermal performance.

Y-Warm delivers high-performance thermal insulation with less bulk, enabling lighter, thinner, and more comfortable products.

By reducing reliance on animal-derived insulation, it expands the possibilities for warmth while supporting more responsible material choices.

A sustainability vision by Y-Warm Technologies.

Zero° Technology is built on a simple principle: technological progress and environmental responsibility should advance together.

By engineering greater performance with fewer resources, materials science can help reduce environmental impact and expand the possibilities for a more sustainable future.

Better technology. Fewer resources. A more sustainable future.

At standard atmospheric pressure, 0°C marks a critical threshold for water.

As temperature drops, molecular motion slows, and a familiar state begins to change.

Zero is more than a number.

It is a boundary and a beginning — a point where one state transitions into another.

Where have we come from — and where are we headed?

Throughout history, technology has continually pushed the boundaries of what humanity can achieve. But progress is not defined by technology alone. What matters is the future it helps shape.

The next chapter of innovation is about achieving more with less — reducing environmental impact while creating lasting value.

Technology expands what is possible.

Responsibility determines where it leads.
