WHAT IS CORK? WHAT ARE THE PROPERTIES OF INDUSTRIAL CORK ROLLS?

Cork is the suberous treatment, suberose parenchyma, or bark, of the species Quercus Suber L., typically known as the cork oak. It is made up of cells of around 42 million/cubic centimeters, which have five wall layers. Cork Oak trees are able to make through for as much as 300 years giving raw materials every nine years from the moment they are twenty years old. The reason for cork’s properties is due to the honeycomb structure of its cell. Every cell is made up of 14-sided polyhedron, loaded with air with a very solid and adaptable membrane layer that is water-resistant and closed. Cork likewise has outstanding electric, thermal, as well as acoustic insulation properties, making it a functional material

  • Elastic, as well as Resilient: The flexibility of the cork cell membranes is extremely versatile, compressible, and elastic, so it will constantly have a tendency to go back to its original shape, no matter what sort of stress it is put under. This makes it a superb item to utilize for bottle stoppers because, if you keep it compressed for years on a bottle’s neck, it still maintains its elasticity and keeps a closed seal. You are going to find this at the time of removing it from the neck of a bottle that it is going to instantaneously swell to its original size, making it hard to fit back into the bottle, no matter exactly how old is the bottle.
  • Lightweight: Concerning 90% of the volume of cork is occupied by air confined in the micro-cells of cork. This encased air comprises concerning 50% of its weight. This makes cork a lightweight product, concerning five times lighter than water. This offers Cork’s low density and makes it drifts on water. Cork’s cell membranes are strong water-tight, which indicates that it won’t absorb water, which makes it great for floats for fishing and various other applications.
  • Thermal, Electrical as well as Acoustic Insulation: Cork’s honeycomb framework is comprised of whole lots or little, covered pockets of air which use amazing thermal, as well as sound insulation residential properties. In its all-natural type, cork is likewise a great fire retardant, although cork dirt is incredibly combustible because here, the cell structure has been broken down. These properties make Cork an excellent selection for industrial, as well as aerospace applications calling for lightweight insulation products.
  • Impermeable: Cork has an all-natural cell membrane layer that makes it totally impenetrable to fluids, as well as gases. This chemical is a combination of fats and heavy natural alcohol known as suberin, which makes it such that no fluid can pass through it, as well as stops it from decaying or weakening over time.
