refrigerated truck body for small truck
Polyurethane foam is the most widely used and excellent insulating material and is usually used in the manufacture of refrigerated truck boxes. This material has low thermal conductivity, good insulation properties and high strength due to its low thermal conductivity. The foam density and bubble diameter of high-quality polyurethane materials are small. Furthermore, polyurethane materials are suitable for a wide range of board manufacturing processes, such as injection foam, bonding and spraying.
