Rubber and plastic seals, though seemingly unremarkable, are indispensable 'invisible guardians' in modern industry and daily life. They are typically made from high-molecular materials such as rubber or plastic, and due to their excellent elasticity, compression deformation resistance, and weather resistance, they are widely used in various scenarios.

Their core mission is sealing. Whether it's the doors and windows of cars, the gaps in household doors and windows, or the joints of refrigerators and cabinets, you can find their presence. They can effectively isolate external rain, wind, dust, noise, and hot and cold air, creating a quieter, cleaner, and energy-saving environment for us.

In addition, some specially formulated seals also have characteristics such as heat resistance, oil resistance, and anti-aging properties, allowing them to play a key role in more stringent industrial fields such as machinery equipment, electronic appliances, and aerospace, ensuring the airtightness, watertightness, and stable operation of equipment.

In short, although rubber and plastic seals are small, they are important components for improving product quality, enhancing user experience, and ensuring safety, truly embodying the concept of 'small parts, great functions'.
