As I came to the Laboratory of Synthetic Leather. I found out the way to differentiate PU (Polyurethane) and PVC (Poly Vnyl Chloride).

First you should clean the surface of the synthetic leather and then bring the synthetic leather near you ear and bend the surface of the synthetic leather so they meet surface-to-surface. Slowly you tap both surface together and release the surface.

If you hear a sound of the surface then it must be a pvc (poly vynl chloride) if it is not it should be the PU (Polyurethane) Synthetic leather
