Cork Granules

Granulated cork is used for a wide variety of applications and can be supplied at a wide range of mesh sizes and densities, ranging from fine powder to 12mm chips. Different densities of the cork granules will determine the properties and hence the end use – lower density cork granules (starting from 60 kg/m3) are more elastic, whilst higher density granules (up to 200 kg/m3) contain more woody elements and are much harder. As a result the lower density of the cork granules, the higher the price. Different cork granules densities are suited to completely different usages. Also available is  cork dust , which are effectively tiny granules that can be blended with a range of products or even for explosives.

Cork granules have some unique properties and some of the lesser known uses of granulated cork are:

Clearing up oil spills – because of its absorbency properties, it can be a very effective way of containing and cleaning up emergency spills.

Filler and Insulator – being light weight, natural and with insulation properties that synthetics cannot match, granulated cork has been used in countless applications.

Gardening – granulated cork can be mixed with the soil to aid aeration, without recourse to synthetic materials.

Creative – cork grain can be used to add texture and organic effects to paint and other displays.

The price of cork granules is largely determined by density as demand for low density cork granules is far higher than for high density, because most of the unique properties of cork are more prevalent in the lower density granules. This means that the cost of low density cork granules will typically be several times that of high density granules. You can find out more about cork granule density here.

Expanded cork is a completely different form of granulated cork and has different properties. Click here for more information and prices for expanded cork granules.You can see prices for expanded cork boards here.
