What is PU Leather?

PU leather, or polyurethane leather, is a synthetic leather created of thermoplastic polymer applied for making furniture, jacket, coat or shoes. 100% PU leather is entirely artificial and is rated vegan. There are some examples of PU leather named bi-cast leather that has exact leather but has a polyurethane cover on top. This type of PU leather takes the fibrous part of cow skin that is extra from making original leather and put a layer of polyurethane on top of it.
