PTFE waterproof breathable membrane material has many excellent properties, which makes it closely related to our daily life and has important and wide applications in many fields.
Let’s take a closer look.
Waterproof and breathable membrane (breathing paper) is a new type of polymer waterproof material.
In terms of production technology, the technical requirements of waterproof and breathable membranes are much higher than those of ordinary waterproof materials. At the same time, from a quality perspective, ptfe waterproof and breathable membranes also have functional characteristics that other waterproof materials do not have.
With the increasing progress and development of social economy, human activity areas have gradually touched every corner of the earth, and the activity time also spans day and night, and is not limited to sunlight lighting conditions.
As a result, a variety of lighting equipment has emerged in response to various actual conditions, creating conditions and providing guarantees for human beings’ colorful outdoor activities and a wide variety of production operations.
PTFE waterproof and breathable membrane is a microporous membrane made of polytetrafluoroethylene as raw material, using special technology, calendering, extrusion, biaxial stretching and other methods.
The pore size of this membrane ranges from 0.02um to 0.2um, and the porosity reaches more than 88%.
In the state of water vapor, the water particles are very small, and these water particles can penetrate all the way down the capillary 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, allowing the waterproof and breathable membrane to truly have a waterproof function.
