What is eptfe waterproof 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 and dustproof breathable membrane is a general name for the waterproof and breathable function of this type of material. The manufacturing process of ePTFE can be simply understood as, firstly, the monomer tetrafluoroethylene is polymerized to form the polymer polytetrafluoroethylene (PTFE), which is commonly known as Teflon. Then, the PTFE is made into porous waterproof, dustproof and breathable membrane materials with different pore sizes through processes such as stretching. The role of EPTFE waterproof, dustproof and breathable membrane Many years ago, ePTFE material has been used in some parts of the car. It not only has the waterproof ability of IPX7/IPX8, even IPX9K, but also can well and effectively solve the need for sealing. The problem of unbalanced pressure difference between the inside and outside of the product, and reduce the condensation problem inside the seal. The functions of ePTFE such as balancing internal and external pressure difference and water vapor transmission can effectively improve the performance and service life of electronic products. Especially in parts with large internal temperature changes and more sensitive to condensation during use, waterproof and dustproof breathable membranes have a high amount of use, such as automotive electronic control units, sensors, motors, etc. EPTFE waterproof and dustproof breathable membrane has a certain dustproof function due to its special microstructure, and can also have a certain oil resistance through surface treatment. In recent years, with the development of science and technology, it has a good A waterproof and dustproof breathable membrane with sound-transmitting function.
