Properties and uses thumb|Cork can be varnished and used for flooring, as an alternative for linoleum, stone, or ceramic tiles Cork's elasticity combined with its near-impermeability makes it suitable as a material for bottle stoppers, especially for wine bottles. Cork stoppers represent about 60% of all cork based production. Cork has an almost zero Poisson's ratio, which means the radius of a cork does not change significantly when squeezed or pulled.
