PE foam reduces vibrations and noise in appliances like washing machines, dishwashers, and refrigerators. Pads or sheets are installed around motors or mechanical parts to minimize operational noise. Additionally, it improves energy efficiency in refrigerators, freezers, and water heaters by preventing heat loss and maintaining temperature stability. PE foam also protects sensitive electronics such as smartphones and laptops during packaging. It is also used for thermal management within devices and reduces noise and vibrations from components like hard drives.
