Bicast leather (also known as bycast leather, split leather or PU. leather) is a man-made material made with a split leather backing covered with a layer of polyurethane that is applied to the surface and then embossed. Because it is only used for the backing, the leather portion of this material generally not visible in finished goods made from Bicast. Bicast was originally made for the apparel industry for glossy shoes, and recently was adopted by the furniture industry. The resulting product has an artificially consistent texture that is easier to clean and maintain, as is the case with most plastic materials.
Production and Features
The use of terms like "leather", "genuine leather" or "100% leather" in relation to this bicast treatment is considered a misrepresentation and therefore not permitted in some countries, e.g., New Zealand. Furniture made with bicast exhibits none of the characteristics associated with aniline leather; it will not develop a patina or suppleness nor otherwise "improve with age". With constant use the polyurethane layer may crack and split free of its backing.
