In high-speed rail transport, melamine foam is widely used as the insulation and anti-freezing layer of the carriage. Its high-efficiency thermal insulation performance can effectively reduce the temperature difference between the inside and outside of the carriage, enhancing passenger comfort. Melamine foam is lightweight, soft, and easy to install, not adding to the train's weight, thereby improving the efficiency of high-speed rail operations. Its strong durability ensures it can maintain excellent thermal insulation for long periods, meeting the demands of high-speed trains running for extended periods at high speeds.
