Applications of PU in the automation industry: Let me explain. What is PU material and its characteristics? . (Crosslinking agent used in PVC artificial leather)

I. What is PU material?

PU-finished leather is made by processing the second and third layers of natural leather, defective leather, through a special film-pasting and pressing process. A polyurethane PU surface layer is applied to the leather surface, resulting in various colors and patterns. It retains the breathability and flexibility of leather, while offering unique visual appeal and waterproof properties. (Crosslinking agent used in PVC artificial leather)

II. Differences between PU synthetic leather and PVC artificial leather

Artificial leather was the earliest substitute for leather materials. It is made by calendering and compounding PVC material, plasticizers, and other additives onto fabric. Its advantages include low cost, rich colors, and diverse patterns. However, its disadvantages are that it is prone to hardening and becoming brittle. PU synthetic leather is used to replace PVC artificial leather and is more expensive. In terms of chemical structure, it is closer to leather materials. PU artificial leather does not require plasticizers to achieve softness, so it does not harden or become brittle. At the same time, it also has the advantages of rich colors and diverse patterns, and is cheaper than leather materials, making it popular among consumers.

Leather materials, PVC artificial leather, and PU synthetic leather can generally be distinguished by two methods: First, look at the back of the material. The back of PVC artificial leather and PU synthetic leather is generally a fabric base (or knitted fabric base), which can be easily seen with the naked eye. Second, use the burning and melting method to distinguish: Take a small piece of material and burn it with fire. Leather materials will not melt, while PVC artificial leather and PU synthetic leather will melt. (Crosslinking agent used in PVC artificial leather)

The difference between PVC artificial leather and PU synthetic leather can be distinguished by soaking in gasoline: Take a small piece of material and place it in gasoline for half an hour. PVC artificial leather will harden and become brittle, while PU synthetic leather will not harden or become brittle. (Crosslinking agent used in PVC artificial leather)
