Both PU leather and PVC leather are simulated leather, that is, artificial leather, but they are not the same. Detailed explanation is given below.
1. Manufacturing process
Compared with PVC leather, the manufacturing process of PU leather is more complicated because the bottom is made of canvas PU material with good tensile strength. It can not only be coated on the bottom, but also include the bottom in the middle, so that the bottom cannot be seen. Ministry exists.
2. Physical properties
Compared with PVC leather, PU leather has better physical properties, better softness, tensile strength, and breathability.
3. Pattern
The PVC leather is hot-pressed by a steel pattern roller; the pattern of the PU leather is first hot-pressed on the surface of the semi-finished leather by a pattern paper, and then the paper leather is separated and surface treated after cooling.
4. Price
The price of PU leather is more than double that of PVC leather, and the price of some PU leather made according to special requirements is even 2-3 times higher.
5. Cost
The pattern paper of PU leather is generally scrapped after 4-5 uses. The pattern roller has a long service life, so the cost of PU leather is higher.
Therefore there is a difference between the two.
