Micro cork ball
Micro cork balls can be used for a wide variety of options, for example, table football, decoration and any other that your fantasy might come up with.
Micro cork balls can be made in Natural, Agglomerated, or Mixed compositions according to whatever you prefer.
“Micro-granulated cork stoppers are new generation cork stoppers with a body of the agglomerated cork of a specific grading. The granules are glued to each other by means of an adhesive approved for contact with food. They are made using a procedure that aims to improve their sensorial neutrality. This stopper’s main characteristic is its high structural stability. It is recommended for wines which will be quickly consumed, but which have some complexity.” (APCOR)
“Granulation: The cork is submitted to a grinding process similar to that for composite agglomerates. The final granule size obtained depends on their intended use, from 3 to 10 mm for acoustic agglomerate and 5 to 22 mm for thermal agglomerate.
Cleaning: Next, impurities are removed, specifically wood and bark pocket, with the aid of densimetric separators and sometimes pneumatic separators or rotating drums. The granulate is stored and dried until the ideal moisture level is reached.
Agglomeration: The granules are placed in autoclaves and, by using steam from water overheated to 300-370 ºC, they undergo expansion and exude their resin (suberin), driving agglomeration without using any foreign additives. Boiling time varies from 17 to 30 minutes, depending on the initial moisture content.
Finishing: The result is expanded cork blocks which, after stabilization, are rectified and cut into sheets of varying thickness, normally using a bandsaw, after which they are adjusted for size and squareness using a circular saw. The blocks are packaged and stored.” (APCOR)
Natural cork ball
Natural cork ball is a versatile and sustainable product. As it is made of cork it is a raw material that is so perfect that, recently, no industry had the chance to replicate it. The natural cork has splendid distinctions from the other products with the same goals. Natural cork is very light with 50% of it is constituted by air, it is elastic and compressible, has a natural touch, is a highly abrasion-resistant, hypoallergenic, thermal insulator, impermeable to liquids and gases, and at last but not least it is a natural raw material that makes it an eco-friendly product.
