Teach you the difference between PU leather and PVC leather

PU leather and PVC leather, often called artificial leather or imitation leather, are made of polyvinyl chloride, but they are not exactly the same.
So do you know how to distinguish PU leather and PVC leather? The following three methods can be distinguished.
1. Observed from the corners, the PU leather base fabric is much thicker than PVC leather.
2. In terms of hand feel, PU leather is relatively soft, while PVC leather is relatively hard.
3. When burned with fire, the smell of PU leather is much lighter than that of PVC leather.
The difference between the two can be seen through these three methods.
