Why Is PU Artificial Leather And PVC Artificial Leather More Environmentally Friendly?

With the continuous development of science and technology, we have made great progress in many aspects, for example, in the production of artificial leather, the more common ones are PU artificial leather and PVC artificial leather, do you know what is the difference between the two? First of all, the production process is different, as well as the price, the scope of application, the feel and taste are also different, so you can distinguish through these ways. Now everyone will choose PU artificial leather products, why is this? Because it is more environmentally friendly, do you know the reason for environmental protection? If you don't know, follow the editor to take a look at the detailed analysis below.

The difference between PU artificial leather and PVC artificial leather:
The price of PU artificial leather is more than double that of PVC artificial leather, and the price of PU artificial leather for some special requirements is 2~3 times higher than that of PVC artificial leather. Generally, the pattern paper required for PU artificial leather can only be used 4~5 times before being scrapped; The service life of the pattern roller is long, so the cost of PU artificial leather is higher than that of PVC artificial leather.

There are also certain differences in the scope of application of these two materials. In terms of footwear, PVC artificial leather is mostly used in lining or non-weight-bearing parts, or in the manufacture of children's shoes, while PU artificial leather can be applied to the fabric of footwear or weight-bearing parts.

In terms of bags, PVC artificial leather is more applicable. This is because the items in the bag are different from the feet worn in shoes and do not emit heat; You don't have to bear your personal weight.

The difference between PU and PVC is relatively easy, and the base fabric of PU is much thicker than that of PVC from the corners, and there is also a difference in the feel, and the feel of PU is softer; PVC feels harder; It can also be burned with fire, and the taste of PU is much lighter than that of PVC.

Reasons why PU artificial leather is more environmentally friendly than PVC artificial leather:
On the whole, PU artificial leather is more environmentally friendly than PVC artificial leather, which is determined by the production of these two synthetic leather raw materials, the raw material for the production of PU artificial leather is polyurethane, polyurethane is an ester polymer organic matter, which is completely non-toxic and harmless to the human body, basically there is no peculiar smell, and the chemical properties of this organic matter are relatively stable and not easy to decompose.

The raw material for the production of PVC artificial leather is polyvinyl chloride, which is the main raw material for plastic products and is also a non-toxic industrial raw material, but polyvinyl chloride is easy to decompose under strong light and high temperature, and will release harmful substances to the human body, which is also the reason why PVC artificial leather will turn yellow and brittle after a long time. These are the reasons why PU artificial leather is more environmentally friendly than PVC artificial leather.

Not all PU artificial leather is more environmentally friendly than PVC artificial leather, and most of them will add some additives to improve the performance of leather fabrics in the leather production process, which is also the main source of harm caused by artificial leather.

PVC artificial leather is a kind of artificial leather that people invented early, and it is also a kind of leather fabric that has developed early in China, the scale of production, on the production process and production technology, it is more advanced than PU artificial leather, some large-scale leather manufacturers use advanced technology to reduce the use of various additives, and produce high-quality PVC artificial leather, which is much more environmentally friendly than PU artificial leather produced by many small workshops.

Now with the rapid development of science and technology, some advanced technologies have emerged, and there is no need to add plasticizers to improve the quality of leather in leather production, and truly realize environmentally friendly leather.
