Pu is a high-molecular compound that is formed by reacting isocyanate groups with hydroxyl groups. It is widely cited and used in the apparel industry due to its resistance to tortuosity, softness, strong stretchability, and air permeability. Pu material is widely used in many industries, and its Chinese name is called polyurethane. It first appeared in the middle of the 18th century and was invented by Germans. However, when it was first discovered, people did not find it useful, but in recent years, this kind of material has begun to shine and has been widely used in various fields. Then Xiaobian will give you simple things. Describe how pu material and pu material package .
How about pu material
Material advantages

At the same time, this material, its texture is closer to our natural leather fabric, it feels exceptionally smooth and soft, and will not become hard and brittle as time goes by. And due to the development of modern production technology, it can also extend a variety of different colors, but also a variety of patterns. Because this material can be produced on a large scale, the cost is low, and the price is relatively low compared to our natural leather fabrics, and it is loved by many people.
Wide range of applications
For example, some leather bags that we can often see, if not some well-known manufacturers of big brands, will generally use this pu material to reduce costs. However, pu material and leather have a certain difference.

And with the different production processes, it can also become a variety of grades. But compared to our dermis, its texture may still have some differences. In general, pu material and leather material have their own characteristics. If it is pu material, the product it produces has a very beautiful appearance, and it is also easier to take care of. The loss phenomenon is also lower, and the price is relative to the leather product. That's a lot lower.
Low price
In addition to making leather bags, pu materials have more extensive uses in other areas. For example, during the construction of some factories, some materials used in the design of some insulation boards are used. At the same time, this material has been added. Flame retardant can play a very good thermal insulation effect. Therefore, the pu material can also be seen in the building materials industry.
Pu material package how to
