Water-proof and Breathable TPU Film
TPU waterproof and permeable membrane is a new type of polymer waterproof material. It is the main material of polyurethane (TPU) and is introduced to hydrophilic base. The surface of the film has no micropores, so it can be protected against wind and water. Because tpu film has a hydrophilic base, it can be permeable through hygroscopic conduction. It is often used in clothing fabrics, home textile composite, mountaineering clothing, ski shoes and other fields.
TPU (Thermoplastic polyurethanes), thermal plasticity TPU elastomer, by including NCO functionality, MDI and OH functionality, POLYOL, 1.4 BG, made by mixing and extruding, with good elasticity, good physical properties, and a variety of mechanical strength is very good, therefore, widely used in injection, extruding, rolling and dissolved into solution such as resin processing way, is the plastic processing industry often use plastic material, made its products cover the range of industrial applications and civil necessities.

Air Permeability VS Vapor Permeability
Different from micro porous permeability film, TPU non-porous hydrophilic film, is to use a sponge in super absorbent “hydrophilic group” quickly will sweat absorption by diffusion, convection way will sweat adsorptive conduction to clothes outer reached through the effect of moisture. Compared with non-porous hydrophilic films, the moisture permeability of porous hydrophilic films is low, but the water-resistant and water-resistant properties of hydrophilic films are better.

ASTM E96 VS JIS L1099
The current methods of moisture permeability are generally used in ASTM E96 or JIS L1099. The numerical value of JIS Method is more significant.
