Ylem—a concept relating to the origins of the universe—provided the initial inspiration for the name Y-Warm.

From imagining primordial matter to exploring the evolution of materials, a question gradually emerged:

Must staying warm depend on greater bulk?

After a long process of scientific research and validation, an insulation material that broke through technical barriers emerged in 2021.

From increasing the “quantity” of material to engineering its “structure.”

Micrometer-scale closed cells are separated by polymer walls of nanometer-scale thickness, enabling highly efficient thermal insulation in an ultra-thin, lightweight form.

What began as a scientific question became a step forward in thermal insulation technology.

For us, extremely low thermal conductivity is only the starting point.

Efficient thermal insulation must also offer water vapor permeability and quick-drying performance.

In conventional insulation materials, these properties often involve trade-offs. Through interdisciplinary research and a break from established thinking, Y-Warm brings these properties together to work in synergy within a single material, challenging the “impossible triangle.”

Making thinness a technology.
Making lightness a performance advantage.

Throughout humanity’s long history of protection against the cold, “more material, greater loft” was seen as the necessary path forward in thermal insulation.

As materials science reaches deeper into the microscopic world, new possibilities emerge for product innovation:

Thinner means greater design freedom.
Lighter means less weight to carry.
Greater efficiency means more effective use of resources.

From apparel, footwear, and outdoor gear to transportation, construction, and industrial applications, ultra-thin, lightweight insulation technology opens new possibilities for product design across industries.

When the Pursuit of Technology Becomes a Lasting Mission

Some say we are too persistent.

We see it as a continuing exploration of the boundaries of materials science.

Some say we are too stubborn.

We see it as the choice to keep searching when conventional approaches offer no answer.

Some say we are too exacting.

We see it as the respect that science and precision deserve—from a material’s macroscopic performance down to its structure at the micrometer and nanometer scales.

Science never rewrites the laws of physics.
We explore the possibilities within those laws that have yet to be fully uncovered.

As materials evolve, they drive the evolution of products.
As products evolve, they open new paths toward a more sustainable industry.

The significance of technology goes beyond creating a new material.

It lies in helping people and the world move toward the future with greater lightness.
