Foam rubber sealing strips are also crucial in the manufacturing of appliances, such as refrigerators, air conditioners, and washing machines. They help in maintaining optimal operating conditions by ensuring that doors close tightly, thereby preventing energy loss. For instance, in refrigerators, these seals prevent cold air from escaping, which is essential for food preservation. Moreover, in more industrial applications, they can be utilized in machinery to reduce vibration and noise, thereby enhancing the overall performance.
