A machine known as a double-belt press is used to bond the cork layers to wafer-thin slate sheets under elevated pressure and temperatures of roughly 180 degrees Celsius.

Natural cork and VINNEX^® powder binder are blended together to form homogenized pellets known as cork-polymer composites or CPCs. VINNEX^® also binds excellently with other natural fibers, such as coconut, leather and wood.

Wafer-thin, flexible slate-cork panel: novel floor and wall coverings are created from natural cork, Indian slate and WACKER's innovative VINNEX® powder binders.
