what is pu leather
From Wikipedia, the free encyclopedia. Bicast leather (also known as bi-cast leather, bycast leather, or PU leather, sometimes described as split leather) is a material made with a split leather backing covered with a layer of polyurethane (hence the term PU leather) that is applied to the surface and then embossed.ecause it is only used for the backing, the leather portion of this material is 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 Bicast was originally made for the apparel industry for glossy shoes, and recently was adopted by the furniture industry.
