Characteristics and application of TEFLEX PTFE microporous membrane

Teflex PTFE microporous filter membranes are mostly produced by bidirectional mechanical stretching process. ePTFE membranes are mainly used for gas and liquid filtration, and are divided into hydrophilic and hydrophobic PTFE membranes according to different industry applications. Due to the softness of the PTFE membrane, it needs to be supported with other membranes, and it is formed by coating or hot pressing. Membranes commonly used for support are composites of PP, PET, glass fiber and other fabric materials, which integrate the functions and characteristics of each membrane layer to improve filtration efficiency, prolong the service life of the membrane, and reduce costs. In order to create greater economic benefits.

What are the characteristics of Teflon membrane? Hydrophilicity and hydrophobicity are its two major characteristics. Here we mainly introduce hydrophobic membrane materials. When hydrophobic membrane materials are in contact with water droplets, the water droplets and the membrane plane form a cut angle greater than 90 degrees. The affinity between water droplets The resultant force is greater than the affinity of the membrane, and it is used to form water droplets that cannot pass through the membrane, which is called hydrophobic membrane material. However, the microporous structure of the membrane can pass through the gas, and PTFE itself has a high porosity and flow rate. It is used as a pressure relief membrane for infusion set filters in the medical industry, and as a balance pressure and temperature in the automotive electronics or lamp industry. filter membrane, etc.

In addition, PTFE membrane has very good chemical resistance and high temperature resistance that other membrane materials cannot match. At the same time, it has very good mechanical properties, so it is used in many other industries.

What are the applications of Teflon membrane?
It is widely used in the precision gas filtration and analysis industry, and is also widely used in the liquid filtration industry, such as the filtration of organic solvents. With its good waterproof and air permeability, it is used as packaging materials in electronics, semiconductor and other industries, moisture-proof and anti-static. In the chemical industry, due to its strong chemical resistance, it is mostly used in some chemical industries with strong corrosion.

Due to the variety and particularity of the manufacturing process of Teflex, its customization methods are also diverse. Different production processes can be customized according to actual needs. The PTFE filter membrane pore size, porosity, and thickness can be controlled by means of process to meet different requirements. The operating environment, such as ePTFE laminated membranes that can be made of woven fabrics, needle felts, filter papers and new filter materials PET, PP, PES, glass fibers, etc.
