Good rain knows the season, and spring will happen.
Sneak into the night with the wind, moisturizing things silently.
Every spring comes with continuous spring rain. While people feel the revival of spring, they also hope to have a jacket that is both waterproof and breathable when they go out.
In fact, it can be done using ptfe waterproof and breathable membrane.
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, allowing the waterproof and breathable membrane to truly have a waterproof function.
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%.
It 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.
The main advantages of polytetrafluoroethylene waterproof and breathable membrane are as follows: 1. It has good high temperature resistance. The temperature of the working environment where the waterproof breathable membrane is used can reach 250°C.
Good low temperature resistance and good toughness.
Two: High lubrication, good corrosion resistance, PTFE film can show resistance to most chemicals and solvents, strong acids, alkalis and various organic solvents.
