A patent illustrating cooling pads of excelsior. Excelsior has many applications, examples include PropertieseditWood wool fibers can be compressed and when the pressure is removed they resume their initial volume. This is a useful property for minimizing their volume when shipping. Due to its high volume and large surface area, wood wool can be used for applications where water or moisture retention is necessary. The width of wood wool fibers varies from 1. In the UK there are specifications for dimensions, p. H, moisture content and freedom from dust and small pieces, set by British Standard BS 2. This standard was originally issued in 1.
