Appliances and commercial refrigeration
When used in appliances and commercial refrigeration applications, polyurethane insulation can help reduce energy loss by restricting heat and cold infiltration. This type of insulation also greatly enhances structural integrity and retards water and moisture, thereby increasing the longevity of any of the products where it is used.
Created by injecting a well-mixed liquid formulation containing polymeric methylene diphenyl diisocyanate (MDI) and a MDI-reacting polyol blend into a shell or cavity, polyurethane insulation can be found in a variety of appliance applications, including refrigerators, freezers, water heaters, picnic coolers and more. Additionally, polyurethane insulation is also used in commercial and residential entry and garage doors.
Approximately 50 percent of the world's food would rot without insulated refrigeration. Growing urban populations require massive investment in the storage, transportation and processing of perishable foods under controlled temperature conditions. Due to their thermal, processing and hygienic advantages, polyurethane/polyisocyanurate insulation are by far the most widely used insulants for refrigeration.
