PU leather, or polyurethane leather, is an artificial leather made of thermoplastic polymer used for making furniture or shoes. 100% PU leather is completely artificial and is considered vegan. There are some types of PU leather called bicast leather that have actual leather but has a polyurethane coating on top. This type of PU leather takes the fibrous part of cowhide that are leftover from making genuine leather and put a layer of polyurethane on top of it.
Artificial leather, also called synthetic leather, is a material intended to substitute for leather in upholstery, clothing, footwear, and other uses where a leather-like finish is desired but the actual material is cost prohibitive or unsuitable. Artificial leather is known under many names, including leatherette, imitation leather, faux leather, vegan leather, PU leather, and pleather.
Artificial leathers are often used in clothing fabrics, furniture upholstery, and automotive uses. One disadvantage of plastic-coated artificial leather is that it is not porous and does not allow air to pass through, allowing sweat to accumulate if it is used for items that will be in continuous contact with a person's body, such as clothing and car seat coverings. One of its primary advantages, especially in cars, is that it requires little maintenance in comparison to leather, and does not crack or fade easily, though the surface of some artificial leathers may rub and wear off with time.
