If you want to get technical, we can go that route, too. SeaCork flooring doesn’t compress or shrink over time. It rebounds from just about anything. That’s typically all you really need to know. For all you engineers out there, we present the following:
45% Suberin : a complex fatty acid, and the principal component of cork, responsible for its elasticity.
27% Lignin : An integral part of the cell walls of cork.
12% Polysaccharides : The part contributing to the texture of cork.
6% Tanins : Determining its characteristic color.
5% Ceroides : The hydrophobic part which helps to ensure its impermeability.
5% Various : Minerals, water, glycerin, etc.
