Breathable Sheet BREATHRON™

Water and wind won't pass through, but air and moisture vapor do. This film truly breathes.

Water and wind won't pass through, but the necessary air is taken in, and moisture vapor is released. BREATHRON combines all of these functions into one material. Its secret comes from a complex mixture of microscopic pores in micron units. <Moisture Permeability and Water Resistance> <Air Permeability and Wind Resistance> This seemingly contradictory combination of features can be controlled upon the customer's request. These capabilities are also used in the adhesive heating pad industry, which requires highly-efficient ventilation and stability. BREATHRON breathable film meets a wide range of applications.
