PTFE nanomembrane is made of polytetrafluoroethylene as raw material, using a special process, after calendering and extrusion A microporous membrane made by stretching, biaxial stretching and other methods. It has the characteristics of high peel strength, large air permeability, and uniform pore size distribution.

Polytetrafluoroethylene (PTFE), commonly known as the “King of Plastics”, has a linear macromolecule structure with almost no branches, and both sides of the macromolecule are C-F bonds. It is a very stable chemical bond. The fluorine atom binds the carbon atoms on the main chain. Shielded and protected, the molecular chain is difficult to destroy. The special molecular structure makes it invulnerable to all poisons. It has good thermal stability, chemical stability, insulation and lubricity. It has a wide applicable temperature range and strong chemical stability. Corrosion-resistant, will not hydrolyze, and has good mechanical properties.

PTFE nanomembrane has a node-fine fiber structure, forming hundreds of millions of micropores per unit area, which can effectively intercept dust in the air and is very suitable for the field of air purification. The filter membrane has high breathability And high interception efficiency enables the vacuum cleaner to not only effectively intercept dust particles, but the highest accuracy can reach H14 level (99.995%) or above. Since the micropore diameter is tens of thousands of times larger than water molecules and hundreds of times smaller than water droplets, it has excellent moisture permeability , breathable and waterproof. It is currently the most widely used microporous organic membrane.

It is a ptfe nanomembrane manufacturer integrating production, sales and customization. The company has advanced PTFE film production lines and composite production lines. The company’s products are widely used in various fields. With strong technical force and strict management system, the company ensures that everything focuses on the interests of users and provides users with high-tech, high-quality, high-performance, and high-level products.
