Rubber and plastic sealing strips, although seemingly unremarkable, are indispensable "invisible guards" in modern industry and daily life. It is usually made of high molecular materials such as rubber or plastic. With its excellent elasticity, compressive deformation resistance and weather resistance, it is widely used in various scenarios. Its core mission is sealing. Whether it's the car doors and Windows, the gaps in the doors and Windows at home, or the joints of refrigerators and cabinets, you can find its presence everywhere. It can effectively block out the wind, rain, dust, noise and cold and hot air from the outside, creating a quieter, cleaner and more energy-efficient environment for us. In addition, some specially formulated sealing strips also possess properties such as high-temperature resistance, oil resistance, and anti-aging, which enable them to play a crucial role in more demanding industrial fields, such as mechanical equipment, electronic appliances, and aerospace, ensuring the airtightness, water tightness, and stable operation of the equipment. In conclusion, although rubber and plastic sealing strips are small, they are important components for enhancing product quality, improving user experience and ensuring safety. They are truly "small parts, big roles".
