The world population is growing, and with it the demand for food and clean drinking water. Reducing the enormous spoilage rates along the supply chain is an important step towards secure access to food worldwide. Covestro is constantly working on insulation foams that provide the basis for a reliable cool chain from harvest to consumer, and that help to save energy in countless households around the globe.

The materials used in the infrastructure of food delivery and storage have a direct impact on how much of a given amount of food perishes before reaching the end consumer. Covestro creates the components for polyurethane rigid foams that are especially well-suited for the cool chain. These materials are used around the globe to insulate warehouses, trucks, refrigerated counters in supermarkets, private refrigerators and freezers. Covestro experts are constantly working on making the high-performance foams perform even better. The most recent innovation in this regard is based on a simple equation: the smaller the pores inside the foam, the better its insulating performance. With microfoam, we were able to reduce the size of the pores – which were extremely small to begin with – by up to 40 percent. The result is a plus of up to 10 percent in the foam’s insulation capability.

Less energy, more space

In this way, microfoam contributes to the battle against food loss on a global scale. On top of that, it helps end consumers save lots of energy in their private homes, as refrigerators and freezers are responsible for no less than one fifth of the average household’s power consumption. And, finally, the innovative foams also make our everyday appliances more practical: because they are thinner than conventional solutions, refrigerators using microfoam provide additional storage room for food and drinks.
