I was unsure where to post this, so the generic discussion section seemed appropriate. I don't know much about chemistry myself, but I have a chemistry related question I am hoping someone could assist me with. I was scrolling the internet and looking at vegan leather options. There are many companies that are using organic materials, such as pineapple, corn, cactus, coffee grounds, etc. and I found that most are made using Polyurethane. My goal would be to eliminate Polyurethane from the equation. I am asking if anyone could point me in the direction of a natural alternative to Polyurethane that could be used in this application. Any assistance would be appreciated. Thank you!
