The difference between pu and pvc and pu
PU: Full of elasticity, full film feel and more delicate than PVC
PVC: poor elasticity, rigid and smelly
Semi-PU: generally refers to PA, the elasticity and film feel are reduced to varying degrees
PU is polyurethane, and PU leather is the epidermis of polyurethane. Nowadays, clothing manufacturers widely use this material to produce clothing, commonly known as imitation leather clothing. PU is the abbreviation of English ployurethane, and the chemical name of polyurethane in Chinese is also good or bad. There are many good bags. Made of imported PU leather;
In our country, people are accustomed to calling artificial leather produced with PVC resin as raw material PVC artificial leather (referred to as artificial leather); artificial leather produced with PU resin as raw material is called PU artificial leather (referred to as PU leather): using PU resin and non-woven fabric as raw materials The artificial leather produced is called PU synthetic leather (synthetic leather for short).
From the analysis of domestic and foreign markets, synthetic leather has also largely replaced natural leather with insufficient resources. The use of artificial leather and synthetic leather to decorate bags, clothing, shoes, vehicles and furniture has been increasingly recognized by the market. Its wide range of applications, large quantities and varieties cannot be satisfied by traditional natural leather.
Most people refer to synthetic leathers other than genuine leather, such as PVC and PU leather, as artificial leather or imitation leather. PVC and PU are both polyvinyl chloride (a type of plastic), but the manufacturing processes of these two products are different.
During the manufacturing process of PVC leather, plastic particles must be hot-melted and stirred into a paste, and then evenly coated on the T/C knitted fabric base according to the specified thickness, and then entered into a foaming furnace for foaming to make it adaptable We produce various products with different softness requirements, and perform surface treatment (dying, embossing, polishing, matting, grinding and fluffing, etc., mainly in accordance with specific product requirements) when they are released.
The manufacturing process of PU leather is more complicated than that of PVC leather. Since the base fabric of PU is a canvas PU material with good tensile strength, in addition to being coated on the base fabric, the base fabric can also be included in the middle to make it There is no base fabric visible from the outside. The physical properties of PU leather are better than PVC leather, including resistance to bending, good softness, high tensile strength, and breathability (not available in PVC). The pattern of PVC leather is hot-pressed by a steel pattern roller; the pattern of PU leather is hot-pasted on the surface of the semi-finished leather with a pattern paper, and then the paper leather is separated after it cools down to make the surface. deal with. The price of PU leather is more than double that of PVC leather, and the price of PU leather with certain special requirements is 2-3 times higher than that of PVC leather. Generally, the pattern paper required for PU leather can only be used 4-5 times before being scrapped; the pattern roller has a long service life, so the cost of PU leather is higher than that of PVC leather.
There are also certain differences in the scope of application of these two materials. In terms of footwear, PVC leather is mostly used in linings or non-weight-bearing parts, or in the manufacture of children’s shoes; PU leather can be applied to footwear fabrics or weight-bearing parts. In terms of bags, PVC leather is more suitable. This is because the items in the bag, unlike your feet in shoes, do not emit heat and do not bear your own weight.
The difference between PU and PVC is relatively easy. From the corners, the base fabric of PU is much thicker than that of PVC. There is also a difference in feel. PU feels softer; PVC feels harder; you can also use fire to burn it. The smell is much lighter than that of PVC.
