With the increasing air pollution, air purifiers have become an indispensable necessity in our lives. So, what is the core of this air filter? Very simply, it is PTFE microporous membrane.
PTFE and ePTFE are both polytetrafluoroethylene, PTFE is just the name of a substance, and ePTFE is the abbreviation of expanded PTFE. It is a product made of PTFE resin raw material processed into a porous structure. It has the characteristics of porous, lightweight, filtering, water blocking, ventilation and pressure relief of expanded objects, so it is called ePTFE. Although the physical and chemical properties of the two are similar (ePTFE has lower density, better bending performance, and better resilience), their structures and uses are very different!
The filtration mechanism of polytetrafluoroethylene microporous membrane is a surface filtration mechanism, which can easily remove dust. The membrane pore size is small and uniform, the microporous structure is stable, and the porosity can reach 80%. ~90%, the filtration efficiency can reach 99.999995%, and the filtration accuracy can reach above U15 level, or even reach U17 level. At the same time, the surface is water-repellent and has a very high water pressure resistance, so it has high waterproof performance.
It is a polytetrafluoroethylene microporous membrane manufacturer that integrates 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.
