Comparison of properties between PVC and Pu leathers

The first generation of artificial leather is PVC, which is cheap and has a certain natural leather texture. However, it has the disadvantages of poor weather resistance, stiff handle and poor softness. It is mainly used in low-end bags, shoes and balls.

The second generation product is pu (polyurethane), which originated from the large-scale application of polyurethane materials in the 1940s. It has the advantages of soft luster, soft handle, strong sense of genuine leather, good cold resistance and so on. It is widely used in the fields of clothing, furniture and high-grade shoes.

The pattern of PVC leather is made by hot pressing of steel pattern roller; The pattern of PU leather is a kind of pattern paper, which is first hot pressed on the surface of semi-finished leather, and then separated from the paper leather after cooling down for surface treatment.

The price of PU leather is more than twice as high as that of PVC leather. The price of PU leather with special requirements is 2-3 times higher than that of PVC leather. Generally PU leather required for the pattern paper can only be used for 4-5 times will be scrapped; The use cycle of pattern roller is long, so the cost of PU leather is higher than that of PVC leather.

There are also some differences in the application scope of these two materials. In shoes, PVC leather is mostly used in the inner material or the parts not bearing the weight, or the manufacture of children's shoes; PU leather can be applied to the fabric of shoes or parts bearing weight. In terms of bags, PVC leather is more suitable. This is because the bag is different from the foot in the shoes, and it will not emit heat; You don't have to bear your own weight.

Pu, PVC is easier to distinguish, from the angle of Pu bottom cloth to be much thicker than PVC, hand feeling also has differences, Pu feel soft some; PVC has a stronger hand feel; You can also use fire to burn. The taste of Pu is much lighter than that of PVC.
