When we go to buy leather furniture, shopping guides often talk about pu skin, then what skin is pu skin, pu is what material, pu leather is what material it? If you do not know these issues, then when you hear the pu skin, you will certainly look awkward. Pu is a polymer compound that reacts with isocyanate groups and hydroxyl groups, because of its resistance to bending and softness. , Stretchability, breathability and a wide range of references and apparel areas, today Xiao Bian will tell you what the material is pu and PU material selection guide, I hope you can learn some knowledge.
What does pu mean?
Pu skin what skin?
PU is polyurethane, is the abbreviation of English ploy urethane, pu leather is polyurethane synthetic leather, commonly used in bags, clothing, shoes, vehicles, car seats, car mats, furniture, leather sofa production, commonly known as artificial leather, Pu leather The striae are very similar to the dermis and have a soft touch. It is difficult for outsiders to distinguish between dermis and regenerated skin. Pu leather is characterized by a beautiful appearance, lower prices, but with the development of technology, Pu skin has also been made into a variety of grades, the price can be compared with the dermis.
Pu leather is what material?
Pu leather is what material? PU leather is the natural leather of the second and third layers of leather, leather and leather by a special membrane film lamination process, the surface of the leather covered with polyurethane PU surface layer, which makes the surface of the leather show a variety of colors, many The pattern, and without losing the advantages of leather breathable, folding, has its own unique appearance and waterproof properties.
The emergence of ultra-fine PU synthetic leather is now the third generation of artificial leather. Its three-dimensional structure network of non-woven fabrics for synthetic leather in the substrate has created a condition to catch up with natural leather. The product incorporates a newly developed PU slurry impregnated, composite surface layer processing technology with an open-cell structure, which exerts a huge surface area and a strong water absorption effect of ultra-fine fibers, enabling the superfine PU synthetic leather to have a bundle-like ultrafine Due to the inherent moisture absorption characteristics of natural leather of collagen fibers, it is comparable to high-grade natural leather in terms of internal microstructure, appearance texture, physical properties, and wearing comfort.
Differentiation methods for leather and artificial leather PU:
Cortex fabrics and PVC artificial leather PU synthetic leathers are distinguished by two methods: First, they are distinguished by the back of the fabrics. The method is PVC artificial leather. PU synthetic leather The general back is the cloth base (or knitted fabric base) can be seen with the eyes; Is to use the method of melting and melting to distinguish, the method is to take a small piece of fabric on the fire, the leather fabric will not melt, and PVC artificial leather PU synthetic leather will melt
PU and artificial leather distinguish method:
The difference between PVC artificial leather and PU synthetic leather can be distinguished by gasoline soaking method. The method is to use a small piece of fabric, put it in gasoline for half an hour, and then remove it. If it is PVC artificial leather, it will become hard and brittle, if it is PU synthesis. Leather will not become hard and brittle.
PU material selection guide
First, the characteristics of PU
China is generally used to use PU resin as the raw material of artificial leather called PU artificial leather, referred to as PU leather. The artificial leather produced using PU resin and non-woven fabric as a raw material is called PU synthetic leather, or simply synthetic leather.
PU leather has excellent performance, it is a kind of artificial leather fabric, artificially synthesized with chemical materials, has a leather texture, very strong and durable, and inexpensive
Second, PU technology
PU fabric manufacturing process is more complex, because PU's bottom cloth is a good tensile strength canvas, PU fabric physical properties, resistance to bending, good flexibility, tensile strength, with breathability. In addition to the PU material, it can be applied to the top of the backing fabric. It is also possible to include the backing fabric in the middle so that the presence of the bottom cloth is not visible.
Third, PU cleaning
The PU must be washed by hand during cleaning, and the water temperature should not exceed 60 degrees. During the cleaning process, it is not appropriate to use a washing machine for cleaning. This will quickly shorten the service life of the PU.
If it is a car seat and other supplies, you can use a cleaning agent to wipe the water.
Fourth, PU maintenance
After the PU is cleaned, it should not be exposed to sunlight. Should be put in a cool, ventilated place for air drying effect. Once exposed to high temperatures, it will be susceptible to discoloration or deterioration, shortening the life and use of the PU.
Fifth, the cost of PU
PU fabric prices are higher, and some special requirements of PU fabrics are 2-3 times higher than PVC fabrics. The pattern paper required for general PU fabrics can only be scrapped with 4-5 times; the life cycle of patterned rollers is long, so the cost of PU leather is higher than that of PVC leather.
Summary: What is the meaning of material pu, PU material purchase guide related information for everyone to introduce here, I hope this article helps everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom. We will answer your questions as soon as possible.

The compressor circulates the refrigerant and increases the temperature and pressure of the gas refrigerant to make it easy to liquefy in the condenser.
The condenser condenses the refrigerant to release heat absorbed in the evaporator.
