Cork - a new environmentally friendly material

Cork is extracted from the protective layer of the skin of the oak tree, the scientific name of cork oak, because of its soft texture, so commonly known as cork. The harvesting of cork is a completely renewable process that does not harm the tree and will naturally regrow after ten years. Cork from the tree when peeled off the general thickness of 4-5 centimeters, the thickest up to 10 centimeters or more, the cross-section of the natural texture, was light yellow.

Cork is a natural material with unique properties, with a variety of excellent physical properties and stable chemical properties, such as: small specific gravity, low thermal conductivity, good sealing, strong resilience, non-toxic, non-odor, not easy to burn, corrosion-resistant and non-moldy, and has a certain degree of resistance to strong acids, alkalis, oil and other properties.

Cork is used in large quantities in construction, and it also boasts many desirable properties, such as flame retardancy, sound insulation, and is very waterproof. This environmentally friendly renewable material is now widely used in our lives, like cork stoppers, cork pads, cork crafts, cork cloth, etc. are often seen in our daily life cork products. Cork can even provide thermal protection for aerospace, accompanied by rockets out of the earth, flying into outer space.

Cork's "mother" cork oak is not only the world's only bark is taken down to continue normal growth of tree species, but also for many plants and animals to provide growth and life space. Iberian lynx like to perch in the cork oak forest, the emperor eagle loves to nest in the cork oak forest. In addition, cork oak forests also play a positive role in preventing desertification, carbon sequestration, and water cycle. Most of the world's existing cork resources are concentrated in the Mediterranean coastal areas, including Portugal's most abundant, the best quality.
