Cold Chain Transportation

Polyurethane materials play a core role in cold chain transportation. With their extremely low thermal conductivity and closed-cell structure, they can significantly reduce heat and cold exchange, effectively maintain the stability of the refrigerated environment temperature, and extend the fresh-keeping period of sensitive goods such as fresh food and medicines. At the same time, polyurethane has excellent chemical stability and anti-aging properties, which can resist harsh conditions such as humidity and corrosion, ensuring the long-term and reliable operation of cold chain equipment. In addition, polyurethane replaces traditional chlorofluorocarbons with environmentally friendly foaming agents, which has both low VOC emissions and energy-saving advantages, contributing to the development of green cold chains.
