Environmentally friendly material ptfe waterproof breathable membrane

As a new type of environmentally friendly material, ptfe waterproof and breathable membrane completely breaks the tradition. It is not only waterproof but also has excellent breathability.

PTFE waterproof and breathable membrane is made through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.

Due to the characteristics of ptfe fibrillation, when performing unidirectional stretching (i.e. longitudinal stretching), the ptfe polycrystalline aggregates begin to extend and form some fibrils. The fibrils are parallel to the stretching direction. At the same time, the fibrils The length increases.

The cross-section of ptfe fibrils is wide and thin, its maximum width is about 100nm, and the smallest fibril is ?0.5??1.0nm.

When the ptfe waterproof breathable membrane is in the state of water vapor, the water particles are very small, and these water particles can penetrate along the capillary tube to the other side, causing vapor permeability.

If water vapor condenses into water droplets, the particles will become larger, and the surface tension of the water droplets will act, and the water molecules will not be able to smoothly leave the water droplets, penetrate and reach the other side. In other words, this process This can prevent water penetration, making the waterproof and breathable membrane truly have a waterproof function.

The waterproof and breathable membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.

According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, and there are up to hundreds of millions of micropores per square centimeter.
