Hindustan Cork | Home


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 wine corks. The process of manufacturing wine 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. HC works with customers to ensure correct mesh size and densities to meet specific needs. HC 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.


It has been found that medium size cork grain is an ideal material to help clean small domestic and industrial spills (oil) since it confines and absorbs spills quickly.


Ideal for use as fillers (ie fill kayak, canoe, and boat cushions). Also used to fill dolls and mannequins.


Mixed with garden earth, cork allows soil to remain loose (aerated) and moist thus more beneficial to healthy plant growth.


Cork grain is used extensively to simulate realistic terrain (sand, dirt) on movie and theater sets. It also is used to texturize paint and create a stucco effect.


Whether designing a “make believe” beach or desert, or an interesting flooring design, cork grain provides display designers with endless possibilities.
