The porous membrane has an air permeability of 1-200 sec/100 cc.
At least some of the filler particles have a lamellar shape, which allows the diffusion capacity to be increased at a predefined air permeability.
The sterilized bag of the invention has excellent air permeability, and can separate contents of the bag from deleterious compositions contained in air.
The environment-friendly plastic of the present invention is biodegradable, has good air permeability, and can adsorb toxic gas and purify air.
The outer mesh wall (3) has a greater air permeability than the inner mesh wall (4).
The waterproof sheet (33) has air-permeability and translucency.
The breathable thermoplastic film imparts water-resistant to the substrate as well as maintains the breathability of the substrate.
This breathable sheet is imparted with oil repellent properties without a significant drop in breathability.
This breathable film is imparted with oil repellent properties without a significant drop in breathability.
For certain applications, the insulation sheeting (10) may be perforated for air and water vapour permeability.
Disclosed are a waterproof structure and a control method of terminal equipment with a built-in air pressure gauge, relating to the field of terminal equipment, and solving the problem of the terminal equipment being waterproof and air permeable.
An elastomeric, breathable laminate having enhanced breathability is formed by bonding a breathable, microporous, extendible/elastic film to a nonwoven facing material.
As a result, it has been discovered that the multilayer film of the present invention can be used to reduce odor in a variety of applications, while still maintaining the desired breathability.
A gas permeability of the body (40, 42) decreases as a function of a vertical orientation of the body (40, 42).
The padding consists of a breathable material so that the harness is air-permeable and comfortable to wear.
Desirable softness, breathability and barrier properties are obtained.
