About Dry Ice - What is Dry Ice?
Dry ice is the solid form of carbon dioxide (CO2). It's called "dry ice" because it does not melt like wet ice. Instead, dry ice converts into carbon dioxide gas. Because dry ice is extremely cold ( -109°F/-78.5°C), non-toxic, and completely dry, it is commonly used as an expendable refrigerant to ship frozen food or medical products or to cool materials during production. The other major use of dry ice is for dry ice blast cleaning, an effective and environmentally friendly way to clean industrial equipment.
