Cork powder / cork dust supplier
Cork dust or cork powder is produced when corks are ground down to size using grinding stones, which results in a very fine powder, which has a variety of uses. It can be used to produce colmated corks, where the dust is used to patch up imperfections in the surface of lower quality natural corks and is also used in the cork industry to power the boilers needed to “cook” the cork bark before it can be processed. There is always some cork dust left over and periodically we wholesale it to various different industries, some who need it because of its highly combustible nature and others to blend it with other products such as plaster to make products benefiting from cork’s unique properties in terms of elasticity, insulation, low density and so on. Cork dust can also be used to make explosions, as the extremely fine dust can hang in clouds in the air, which will ignite if exposed to a naked flame.
The size of cork dust particles are around 200 microns, but please understand that cork dust is a byproduct of the cork production process so there is not the kind of very accurate control over particle size that there is in the case of cork granules for example.
So if you are looking for a cork dust supplier then we are able to supply in quantities of 25kg for samples, although generally we supply a minimum of one pallet, which is 180kg (either in bigbags or sacks). We are also able to supply by the container if require and and we generally always have stock available. Please contact us at CorkLink for more information. We also supply a full range of cork granules in different densities and sizes if required.
