ePTFE Waterproof and Venting Membrane

ePTFE waterproof and breathable membranes are extensively utilized in electric vehicles, electronic components, lighting fixtures, and sealed outdoor enclosures, where they serve as critical venting valves. Their primary function is to mitigate issues like internal condensation and the effects of pressure differentials ("breathing effect") caused by fluctuating external weather and temperatures. By enabling continuous air exchange, these ePTFE materials rapidly equalize the pressure between the interior and exterior of equipment. This results in an improved operational environment for internal components, enhancing overall device reliability and extending service life.
