Granulated Cork

Cork is the bark of the cork oak tree. This tree produces a layer of cork every 9 years, so taking the bark off does not kill the tree. The bark is then used to make corks. The process of manufacturing corks results in corks and cork waste. 70% of the bark ends up as cork waste. Granulated cork is made from only the waste by-product of industrial cork production. 
Cork grains are used for a variety of industrial components such as batteries, various fillers, insulators, or as compounds to be mixed with other materials. Granulated cork is natural and light in weight. Exact mesh sizes and densities are produced to meet customer’s specifications and requirements. ICI works with customers to ensure correct mesh size and densities to meet specific needs.ICI supplies cork grain in many different sizes ranging from the finest “powder” to large 12mm (1/2”) chips. Cork grain is also available in either a light natural color or a dark brown color. It is normally packed loose in bags or compressed in bales
