korkkimateriaali

Korkkimateriaali, commonly known as cork, is a buoyant, waterproof, and fire-resistant material harvested from the bark of the cork oak tree (Quercus suber). The cork oak is primarily found in the Mediterranean region, with Portugal being the largest producer. The bark can be harvested sustainably without harming the tree, which can live for over 200 years and regrow its cork layer approximately every nine years.

The primary component of cork is suberin, a waxy substance that gives cork its unique properties. This cellular structure, composed of dead cells with air-filled cavities, makes cork lightweight, compressible, and elastic. These characteristics have led to its widespread use in various applications.

Historically, cork's most famous use has been as stoppers for wine bottles, owing to its ability to create a tight seal, preventing oxidation and leakage. Beyond stoppers, cork finds applications in flooring and wall coverings due to its natural insulating properties, durability, and acoustic dampening capabilities. It is also used in fashion accessories like handbags, wallets, and shoes, as well as in bulletin boards, yoga mats, and even in aerospace for its thermal insulation. The material is also biodegradable and renewable, making it an environmentally friendly choice.
