Characteristics of pu materials, the difference between pu materials, pu leather and natural leather, PU fabric is a simulated leather fabric, synthesized from artificial materials, with the texture of genuine leather, very strong and durable, and inexpensive. People often say PU leather is a kind of leather material, such as PVC leather, Italian leather bran paper, recycled leather, etc. The manufacturing process is slightly complicated. Because the PU base fabric has good tensile strength, in addition to being coated on the base fabric, the base fabric can also be included in it, so that the existence of the base fabric cannot be seen from the outside.
Characteristics of pu materials
1. Good physical properties, resistance to twists and turns, good softness, high tensile strength, and breathability. The pattern of PU fabric is first hot-pressed on the surface of semi-finished leather with a patterned paper, and then the paper leather is separated and surface treated after cooling down.
2. High air permeability, the temperature permeability can reach 8000-14000g/24h/cm2, high peeling strength, high water pressure resistance, it is an ideal material for the surface and bottom layer of waterproof and breathable clothing fabrics.
3. High price. The price of some PU fabrics with special requirements is 2-3 times higher than that of PVC fabrics. The pattern paper required for general PU fabrics can only be used 4-5 times before it is scrapped;
4. The service life of the pattern roller is long, so the cost of PU leather is higher than that of PVC leather.
The difference between PU material, PU leather and natural leather:
1. Smell:
PU leather has no fur smell, only the smell of plastic. However, natural animal leather is different. It has a strong fur smell, even after processing, it will have a strong smell.
2. Look at the pores
Natural leather can see patterns or pores, and you can use your fingernails to scrape it and see the erected animal fibers. Pu leather products cannot see pores or patterns. If you see obvious traces of artificial carving, it is PU material, so we can also distinguish it by looking.
3. Touch with your hands
Natural leather feels very good and is elastic. However, the feel of PU leather is relatively poor. It feels like touching plastic and has extremely poor elasticity. Therefore, the real and fake leather can be judged by bending the leather product.
