PRODUCT.09PE Porous Film (BREATHRON)

A Truly Breathable Film That Allows Air and Moisture to Pass through without Passing Water

Although "BREATHRON" does not allow water to pass through, it takes in necessary air and ejects moisture. "BREATHRON" achieves these functions in a single material. The secret behind this achievement is the intricately bent and entangled microscopic pores. <Moisture permeability and waterproof properties> We control these seemingly contradictory functions to meet customer requirements. Situations in which our breathable film "BREATHRON" is used is increasing throughout our daily lives. "BREATHRON" is also used for stick-on heat pads which can be used without needing to rub them against your skin.

Examples of Application

Disposable Heat Pad

Permeates air to supply oxygen to heating elements such as an iron powder inside. Humidity and duration can be adjusted by the size of the micropores.

Room Fragrance

"BREATHRON" permeates and diffuses a vaporized fragrance. It is waterproof so it doesn't spill even liquid fragrances.

Dehumidifying agent

The calcium chloride inside absorbs the moisture in the air through "BREATHRON". The accumulated liquid does not spill even if the container falls.
