During the industrial production process, filtration is performed, and the quality of the filter material also determines the quality of the product.
Therefore, it is particularly important to choose a high-quality and efficient filter material.
The polytetrafluoroethylene filter membrane is a microporous film produced by special processes such as premixing, extrusion, calendering, and biaxial stretching using polytetrafluoroethylene dispersion resin.
Coupled with special treatment, the filter membrane has a series of advantages such as high efficiency, low resistance, anti-pollution, uniformity and stability.
Unique node fibrillation, smooth surface, chemical resistance, large air permeability, wide chemical applicability, biological safety and pyrogen control.
1. The porosity can reach 80%~90%. The porosity is high and the microporous structure is stable.
2. Surface filtration mechanism, easy dust removal membrane has small pore size, small and uniform pore size.
3. The pore size of the membrane is small, and the material has been heat-set at high temperatures, resulting in a stable microporous structure, so it can effectively intercept dust particles at high wind speeds.
?4. The polytetrafluoroethylene filter membrane material is highly hydrophobic and has good non-adhesion. It is easy to remove dust accumulated on the surface of the material. It can be washed with water to restore its performance, achieve reuse and extend its service life.
? is a manufacturer of polytetrafluoroethylene filter membrane materials that specializes in R&D, production and sales.
Our product materials are all imported raw materials, with high uniformity, stable performance and good breathability.
It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
Laminating processing can be carried out according to the coating substrate specified by the customer or the coating substrate provided by the customer.
The key to its technology is the optimized combination of pressure ratio, speed ratio, operating temperature and other parameters. Our company can realize online control of thickness, air permeability and void ratio according to the pore-forming medium and ratio to meet the different needs of users.
