The working principle and performance advantages of ptfe waterproof and breathable membrane

PTFE waterproof and breathable membrane is a new type of polymer waterproof material.

In terms of production technology, the technical requirements of PTFE membranes are much higher than those of general waterproof materials; at the same time, from a quality perspective, waterproof and breathable membranes also have functional characteristics that other waterproof materials do not have: 1. High temperature resistance The effect is good, and the working environment temperature of the waterproof and breathable membrane can reach 250°C.

2. Good low temperature resistance and toughness. The waterproof and breathable membrane has good mechanical toughness. Even if the temperature drops to about -200°C, it can maintain an elongation of 5%. 3. Good corrosion resistance and waterproof The breathable membrane can show resistance to most chemicals and solvents, strong acids and alkalis, and various organic solvents.

4. High lubrication effect is good, and the waterproof and breathable membrane has the highest friction resistance among most solid materials.

5. While the waterproof and breathable film enhances air tightness and water tightness, its unique breathability can quickly discharge water vapor inside the electronic structure and protect the performance of electronic products, thereby truly reducing the loss of electronic components and avoiding It is a new environmentally friendly and energy-saving material that is waterproof, breathable and sound-permeable at no unnecessary cost.

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.

Suzhou New Material Technology Co., Ltd. is a high-tech enterprise specializing in the research, development, production and sales of PTFE waterproof breathable membrane. It has a group of professional polymer R&D teams, strong R&D capabilities, and has multiple invention patent certificates and practical models. patent certificate.
