Ylem—a concept of the primordial matter of the universe—first inspired the name Y-Warm.

From imagining matter to exploring how materials evolve, one question gradually came into focus:

Must warmth depend on thickness and bulk?

After years of scientific exploration and research, a material technology that reduces heat transfer through microstructural design emerged in 2021.

From adding more material to engineering better structure.

Micrometer-scale closed cells are separated by polymer walls just nanometers thick. This microstructural design enables 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 beginning.

Efficient thermal insulation must work together with water vapor permeability and quick-drying performance.

In conventional insulation materials, these properties often involve trade-offs. Through interdisciplinary research, we explore the relationship between structure and performance, bringing these properties into a new balance within a single material.

Thinness, engineered.
Lightness that delivers.

Throughout humanity’s long history of keeping warm, more material, greater thickness, and higher loft have offered a natural path forward.

As materials science advances 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.

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 does not rewrite the laws of physics.
We explore the possibilities within them that have yet to be fully discovered.

By advancing materials, we advance products.
By advancing products, we open new paths toward a more sustainable industry.

The value of technology extends beyond creating a new material.

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