what is eptfe vents

Manufacturing method of eptfe vents ePTFE is a general term for materials with special functions obtained by processing polytetrafluoroethylene (PTFE) materials. Eptfe vents is a general term for the waterproof and breathable functions 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 vents Many years ago, ePTFE material was used in some parts of automobiles. It not only has the waterproof ability of IPX7/IPX8, even IPX9K, but also can solve the problem of products that need to be sealed well and effectively. Unbalanced pressure difference between inside and outside, and reduce 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. Due to its special microstructure, eptfe vents have a certain dust-proof function, and can also have a certain oil-proof ability through surface treatment. In recent years, with the development of science and technology, it has a good sound-permeable function The eptfe vents.
