Which 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, and the quality of PU leather is better than that of PVC leather. Even the cowhide regenerated leather, that is, the leather made from the scraps of cowhide, is also made of PU and PVC on the surface, which is also of good quality.

The manufacturing process of PU leather is more complicated than that of PVC leather. Since the PU base fabric is a canvas PU material with good tensile strength, it can be coated on the top of the base fabric, and the base fabric can also be included in the middle to make it invisible to the base fabric. The physical properties of PU leather are better than PVC leather. It is resistant to torsion, softness, tensile strength and breathability.

How to distinguish PU leather from PVC leather

The distinction between PU and PVC is relatively easy. Judging from the corners, PU base cloth is much thicker than PVC, and the hand feel is different; PU has a softer hand feel, while PVC is harder; it can also be burned with fire, and PU has a much lighter smell than PVC.

It can be distinguished by the method of soaking 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 be hard and brittle; if it is PU synthetic leather, it will not be hard and brittle.

There are also some differences in the scope of application of these two materials. In 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 for footwear fabrics or load-bearing parts. For luggage, PVC leather is used more. This is because the items in the bag, unlike the feet worn by the shoes, do not radiate heat and do not carry personal weight.
