Agglomerated Cork Stoppers. …
Agglomerated stoppers might be fabricated by individual moulding or by extrusion. The agglutinating substance utilized to bind the cork granulates in both of these techniques is authorized for usage in materials that enter into call with foods.
Use, feature and range of agglomerated cork
Agglomerated Cork Features
The quality as well as substance of agglomerated cork, depends upon the type of granules used (granularity as well as specific weight) in addition to, but generally, of the careful binding and stringent manufacturing procedure. CORKSCREWS, with its cutting-edge technology and sophisticated machinery, manufactures by electronic pressing and also various agglutination techniques, the most various kinds of agglomerated cork, with different formulations for all functions, in ideal coordination with international guidelines as well as market demands.
Agglomerated Cork Main Uses
Its utilization is vast as well as unlimited. Into one of the most sophisticated gasket for the auto, aeronautics, electric markets; into the most specific construction system, as decor, under carpeting and parquets; development joints, and so on. for better comfort in the footwear industry, also ideal for bulletin board system, into unlimited variety of present ware, etc.
Agglomerated Cork Range
Originally manufactured in block shape (rectangular), they could be sliced afterwards by very precision equipment in various thicknesses transforming them in sheets beginning with: 0.75 mm up. Nonetheless, some qualities are not offered below 1.5 mm density. For your specific requirement/application, our technical department will offer the necessary guidance.
Do you know ?
Expanded agglomerate, additionally known as black agglomerate, is made by means of the agglutination of virgin cork granules, mainly from the trimming of oak trees, with a higher focus of attractiveness than various other kinds of cork, which act as an all-natural adhesive. It is accomplished with an industrial process without using additives as well as it is 100% natural.
Granulation: The cork is sent to a grinding process similar to that for composite agglomerates. The last granule size gotten depends upon their intended usage, from 3 to 10 mm for acoustic agglomerate and 5 to 22 mm for thermal agglomerate.
Cleaning: Next, impurities are removed, specifically wood as well as bark pocket, with the aid of detriment separators and occasionally pneumatic separators or rotating drums. The granulate is kept and dried out up until the optimal dampness level is gotten to.
Agglomeration: The granules are placed in autoclaves and, by using heavy steam from water overheated to 300-370 ºC, they go through expansion and also emanate their material (suberin), driving agglomeration without making use of any kind of international ingredients. Boiling time differs from 17 to Thirty Minutes, relying on the preliminary moisture material.
Finishing: The result are expanded cork blocks which, after stabilisation, are rectified as well as cut right into sheets of varying density, usually utilizing a bandsaw, after which they are adjusted for size and also squareness using a round saw. The blocks are packaged as well as stored.
