Functions of Automotive ePTFE Vents - Wuxi Sinceriend New Material Technology Co., Ltd.

Automotive ePTFE Vents have a variety of important functions, mainly including the following aspects:
Pressure balance
During the driving process of the car, the internal components will cause pressure fluctuations due to factors such as temperature changes and changes in altitude. ePTFE vents can quickly respond to these changes, allowing air to flow in and out of the sealed space, thereby balancing the pressure, preventing problems such as shell deformation and seal damage caused by pressure differences, and ensuring the structural integrity and normal operation of related parts of the car.
Waterproof and breathable
ePTFE material has a unique microporous structure, which is smaller than the diameter of a water molecule but larger than the diameter of an air molecule. This allows the vents to allow air to pass freely while effectively preventing water from intruding. Even in harsh conditions such as heavy rain and car washing, it can prevent moisture from entering sensitive parts inside the car, such as electronic control units and sensors, to avoid short circuits and corrosion caused by water ingress, and improve the waterproof performance and reliability of the parts.
Filter protection
It can act as an efficient filter to block tiny particles such as dust, pollen, and oil from entering the interior of the car. When a car is driving, pollutants from the external environment are easily sucked into the car or attached to the surface of components. The ePTFE vents can block these impurities outside, protecting internal electronic equipment and mechanical components from pollution and wear, extending their service life, and maintaining the stability of the car's overall performance.
