Applications

Wood wool can be used as is, or it can be a raw material for the production of other products.

Wood wool or excelsior has several applications in packaging, cushioning, stuffing of stuffed animals, for the cooling pads in home evaporative cooling systems known as swamp coolers. mats for ditch control - erosion control (ECM-Erosion Control Mats) and also for the production of bonded wood wool boards.

The width of these fibers varies from 1.5 to 20 mm, while their length is usually around 500 mm (depending on the production process).

When these fibers are bonded with cement or magnesite, bonded wood wool boards are produced. Slabs of bonded wood wool are considered environment friendly construction and insulation materials because they do not contain organic binders.

Properties

The fibers of wood wool can be compressed and when pressure is removed, they resume their initial volume. This is a useful property for minimizing freight.

Due to high volume and large surface area, wood wool can be used for applications where water / moisture retention is necesary.
