The polyurethane film is defined as a breathable membrane, which allows our body's
perspiration to escape, a process referred to as water vapor transmission.
The microscopic pores prevent the penetration of liquids but interconnected
pores allow transmission of these vapors.
The polyurethane film also performs as a barrier, not allowing the penetration
of « Dust Mites » The barrier will assist in cutting off the manifestation
of the mites, however, it is not a complete solution to eliminating
the challenge of « Dust Mites » (Please refer to our Zip & Block
Anti-Allergen products for all the necessary information). |
