What is PU Coated Leather?

Polyurethane, or PU coated leather is split synthetic leather that is bonded and covered with a polyurethane coat, so as to be called PU coated leather. It is often embossed with grain patterns to simulate the texture of top grain leather. PU is also known as bicast leather.







 
PU coated leather is a cheaper alternative to top grain and aniline leather. This material is used mostly for glossy shoes and upholstery. While purists may scoff at PU coated leathers because it is merely faux leather, it does simulate the texture and appearance of natural top grain or aniline leather to a certain extent, while it is much easier to clean and can be applied in different colors. However, real leather will become supple and grow patina over time while pu leather tends to crack exceeding lifespan.
Split leather are essentially a by-product of leather manufacturing. The skin of a cow is removed in a single layer in a slaughterhouse and is then taken to a tannery for processing. The outer layer, which will eventually become aniline or top grain leather, is shaved off, leaving the inner layers behind. These inner layers are called split hides, and to make them useful, they are coated with a layer of polyurethane. The resulting material is then used for affordable handbags, belts, shoes and furniture upholstery.
