Comparison of properties between PVC artificial leather and Pu artificial leather
Author:
Comparison of characteristics between PVC artificial leather and Pu artificial leather the first generation of artificial leather is PVC (PVC), which is cheap and has a certain natural leather texture, but it has the disadvantages of poor weather resistance, stiff hand feel and poor softness. It is mainly used in the field of low-end luggage, shoes and balls.
The second generation product is pu (polyurethane), which originated from the large-scale application of polyurethane materials in the 1940s. It has the advantages of soft gloss, soft hand feeling, strong leather feeling and good cold resistance. It is widely used in the fields of clothing, furniture and medium and high-grade shoes.
The pattern of PVC leather is hot pressed by steel pattern roller; The pattern of PU leather is first hot pasted and pressed on the surface of semi-finished leather with a kind of pattern paper, and then separated the paper leather after cooling down for surface treatment.
The price of PU leather is more than twice that of PVC leather, and the price of PU leather with special requirements is 2-3 times higher than that of PVC leather. Generally, the pattern paper required for PU leather can only be used for 4-5 times and will be scrapped; The service cycle of patterned roller is long, so the cost of PU leather is higher than that of PVC leather.
The scope of application of the two materials is also different. In terms of footwear, PVC leather is mostly used in lining or non weight bearing parts, or in the manufacture of children's shoes; PU leather can be applied to the fabric of shoes or parts bearing weight. In terms of bags, PVC leather is more suitable. This is because the items in the bag are different from the feet in shoes and will not emit heat; No need to bear personal weight.
It is easy to distinguish between Pu and PVC. From the corners, the bottom cloth of Pu is much thicker than PVC, and there are also differences in hand feeling. Pu feels softer; PVC feels harder; You can also burn it with fire. The taste of Pu is much lighter than that of PVC.
