Selection factors of ECU Adhesive Vents - Wuxi Sinceriend New Material Technology Co., Ltd.

① Consideration of fit and stability
Pay attention to the characteristics of the adhesive material. High-quality ECU Adhesive Vents use a special formula that can fit tightly with the ECU shell under vehicle vibration and bumpy conditions. Check the description of the adhesive strength and temperature range in the product description to ensure that the viscosity is stable at different ambient temperatures and will not soften and fall off due to high temperature or lose viscosity at low temperature. At the same time, understand whether the installation method is simple and can quickly reach a stable state after installation to avoid subsequent displacement affecting the ventilation effect.
② Identification of waterproof and breathable performance
The waterproof and breathable membrane is the core. Check the microporous structure of the breathable membrane. Its diameter should be smaller than the water droplet size to prevent water from entering, and at the same time be large enough to allow gas molecules to pass through. You can refer to the product waterproof grade certification, such as the IPX standard. The higher the grade, the stronger the waterproof performance. In terms of breathability, check the gas flow data per unit time. A large flow means good heat dissipation and pressure balance, which can better maintain a suitable environment inside the ECU.
③Weather resistance evaluation
The vehicle operating environment is complex, so you should choose products with good weather resistance. At high temperatures, the vent structure and viscous materials do not deform or soften; at low temperatures, the materials do not become brittle and the breathable membrane remains flexible. Ask for the product's performance test data under high and low temperature environments, such as high temperature exposure and low temperature freezing. Viscosity, breathability and structural integrity ensure stable operation in different climates such as cold and tropical regions.
