There are a number of different types of industrial foam, such as polystyrene packing peanuts, polyurethane foam-in-bag, polyurethane foam-in-place systems, and spray foam insulation. In this article, we will discuss these foams and what they are used for.
Packaging foam is designed to protect items during shipment. What type of foam is needed depends on the item being shipped. Expanded polystyrene foams are lightweight and of a stiffer consistency, making it better suited for less fragile items of a lighter weight. Polystyrene packing peanuts are able to fit into any shape of box, but shouldn’t be used to protect electronics due to the fact that they can conduct static electricity. They also allow for some movement, and therefore shouldn’t be used on smaller items that could break if they shift. Polyurethane foam is commonly used to protect the most breakable of items, thanks to its ability to cushion and be formed into a variety of shapes.
Insulation foam, which is made from polyurethane as well, is used to seal off and insulate an area. A properly insulated building can save a home or business owner up to 40% on energy costs, reduce the chances of mold and pest infestation, keep dust at a minimum, and prevent moisture damage. It is designed to be sprayed so that it can get into hard to reach areas. It locks itself into place without the need for another adhesive, and expands as it dries, ensuring that a proper seal is formed.
