Which one is better, pu leather or artificial leather? How to distinguish PU leather and PVC leather? PU is originally artificial leather. The surface of artificial leather is mainly divided into PU and PVC. PU leather has better quality than PVC leather. Even cowhide recycled leather, which is leather made from crushed cowhide scraps, is also made of PU and PVC. The quality of PU is also good. PVC is generally made of low-end products and is easy to crack or peel.
The manufacturing process of PU leather is more complicated than PVC leather. Since the PU base fabric is a canvas PU material with good tensile strength, it can be coated on top of the base fabric, and the base fabric can also be included in the middle to make it look invisible to the base fabric. The physical properties of PU leather are better than PVC leather. It offers flex resistance, softness, tensile strength and breathability.
How to distinguish PU leather from PVC leather
Between PU and PVC The distinction between them is relatively easy. From the corners, the PU base fabric is much thicker than PVC, and the feel is also different; PU feels softer, and PVC is harder; it can also be burned with fire, and the smell of PU is much lighter than that of PVC.
It can be distinguished by soaking it in gasoline: use a small piece of fabric, put it in gasoline for half an hour, and then take it out. If it is PVC artificial leather, it will become hard and brittle; if it is PU synthetic leather, it will not become hard and brittle.
There are also certain differences in the application scope of the two materials. In terms of footwear, PVC leather is mainly used for linings or non-load-bearing parts, or in the manufacture of children’s shoes. PU leather can be used in footwear fabrics Or load-bearing parts. When making bags, PVC leather is used more. This is because the items in the bag are different from the feet worn by the shoes, so they do not dissipate heat and do not need to bear personal weight.
