With the widespread application of modern electronic devices and intelligent devices, many devices need to work in harsh environments such as high humidity, drastic temperature changes, and chemical corrosion. Especially for core components such as automotive electronic modules, power communication connectors, and sensors, they not only require highly precise performance, but also strong environmental adaptability.
In these application scenarios, the intrusion of moisture and pollutants may cause circuit board short circuits, performance degradation, and even equipment failure. Meanwhile, mechanical stress, temperature shock, and long-term aging can also pose a threat to the reliability and lifespan of the product. Therefore, it is particularly important to develop a high-performance sealing material that can fully meet the needs of sealing, insulation, waterproofing, and moisture resistance.
