What is eptfe waterproof and breathable membrane

Manufacturing method of EPTFE waterproof, dustproof and breathable membrane ePTFE is a general term for materials with special functions obtained by processing polytetrafluoroethylene (PTFE) materials. EPTFE waterproof, dustproof and breathable membrane is a general term for the waterproof and breathable function of this type of material. The manufacturing process of ePTFE can be simply understood as that the monomer tetrafluoroethylene is polymerized to form the polymer polytetrafluoroethylene (PTFE), which is often called Teflon. Then PTFE is made into porous waterproof, dustproof and breathable membrane materials with different pore sizes through stretching and other processes. 2. The role of EPTFE waterproof, dustproof and breathable membrane. Many years ago, ePTFE material has been used in some parts of automobiles. It not only has the waterproof ability of IPX7/IPX8, even IPX9K, but also can solve the need to do it well and effectively. The unbalanced pressure difference between the inside and outside of the sealed product and reduce the condensation inside the seal. ePTFE has the functions of balancing internal and external pressure differences and water vapor transmission, which can effectively improve the performance and service life of electronic products. Especially in parts that have large internal temperature changes and are more sensitive to condensation during use, waterproof, dustproof and breathable membranes are used in a high amount, such as automotive electronic control units, sensors, motors, etc. EPTFE waterproof, dustproof and breathable membrane has a certain dustproof function due to its special microstructure, and it can also have a certain oilproof ability through surface treatment. In recent years, with the development of science and technology, it has a very good Waterproof, dustproof and breathable membrane with excellent sound transmission function
