Wood wool is the name of a product from wood, wood fibers, scrapped from wood logs . Mainly in north America, this product is known by the name Excelsior or "Excelsior wood" or "wood Excelsior", even thought its US commodity code is named "Wood wool (excelsior)". Wood wool can be used as is (or with minor processing), or it can be a raw material for the production of other products.

Applications

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.

Production

Wood wool can be produced in either horizontal shredding machines or in vertical shredding machines

A possible further processing option, is washing in order to remove dust

Wood wool processing may involve drying, to achieve lower moisture
