In recent times, many new materials have appeared, so that the items with higher cost in the past have gradually changed in price, especially in shoes and pipes.

 

Of course, some materials seem to be in good condition. After investigation, you can understand what some of the factors are.

 

For example, the two materials of pvc and pu, many people have always had doubts, so the difference between pvc and pu materials?

 

The difference between pvc and pu materials

 

PU leather is more complicated than PVC leather in manufacturing process. Because the PU base fabric is a canvas PU material with good tensile strength, in addition to being coated on the top fabric, the base fabric can also be included in the middle to make it The appearance can not see the existence of the cloth.

 

1. The physical properties of PU leather are better than PVC leather, resistant to tortuosity, softness, high tensile strength, and breathable (no PVC).

 

The pattern of PVC leather is formed by hot pressing of steel pattern rollers. The pattern of PU leather is hot pressed on the surface of semi-finished leather with a kind of pattern paper. After waiting for cooling, the paper leather is separated and surface treated.

 

The price of PU is more than double that of PVC, and the price of PU leather with some special requirements is 2-3 times higher than that of PVC leather.

 

Generally, the pattern paper required for PU leather can only be scrapped after 4-5 times. The use period of the pattern roller is long, so the cost of PU leather is higher than that of PVC leather.

 

2. The way of distinguishing PU and PVC is relatively easy.

 

From the corners, the base fabric of PU is much thicker than PVC. There is also a difference in the feel. The feel of PU is softer. PVC feels harder.

 

You can also use fire to burn, the taste of PU is much lighter than that of PVC.
