Gluing

(Bonding granules through ‘autoclaving’)

The other method of creating bonded agglomerated cork is to mix the granules with an adhesive. Typically, the percentage of binder is the range of 2% by volume. The mixture is placed in a heated mold and compressed under pressure. Once the press is released, the material is effectively cured (though it would need to cool). By using natural cork granules (that are un-altered – ie: not going through the autoclave expansion), the material tends to have a higher density. The adhesive bonded material tends to be cleaner (aesthetically and physically), and used more for decorative, interior and high-touch applications.
