[ 1 ] [ 2 ] [ 3 ] I det andra fallet är det djurhud ( läder ) som är bunden till polyuretan , också kallat "bycast läder", "bundet läder" eller "splittläder". Polyurethane (PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available. 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.

Polyuretan je polymer, který se vyrábí polyadicí diisokyanátů a dvoj – nebo vícesytných alkoholů za vzniku karbamátové (uretanové) vazby.. Izokyanáty velmi snadno reagují se všemi sloučeninami, které obsahují aktivní vodík (což je např. voda, alkoholy, fenoly, thioly, aminy, karboxylové kyseliny aj.). Hlavní růstová reakce je proto doprovázena řadou vedlejších
