Consumers usually outside the synthetic leather, such as leather PVC, PU leather collectively referred to as leather or imitation leather, but the two are not the same product technology.
In the manufacturing process, PVC leather first plastic particles melt Ban Cheng paste, according to a predetermined uniform thickness of the coating on the T / C knitted fabric substrate, and then into the foaming furnace for foaming to have to adapt production of a variety of different products, softness different requirements, in baked surface treated simultaneously dyeing, embossed, polished, matting, grinding, raising, mainly in accordance with the specific requirements for the product.
 PU leather in the manufacturing process more complicated than PVC leather, PU base fabric is due to the tensile strength of good canvas PU material, in addition to the above coated base fabric, base fabric may also be included in the middle, so that From the appearance of fancy cloth not exist in the end, than the physical properties of PU leather PVC leather and good resistance to take off, good softness, tensile strength, breathability, PVC-free. PVC leather pattern is formed by pressing steel pattern roll. PU leather pattern is a pattern paper, the first heat pressed against the surface of semi-finished leather, etc. After cooling down, the semi-finished leather and paper separation, do surface treatment, PU leather, PVC leather than the price more than twice as high, PU leather than the price of some of the special requirements of PVC leather is 2 to 3 times. General PU leather pattern paper needed only 4 to 5 times will come with retirement, and long life cycle pattern roll, and therefore higher than the cost of PU leather PVC leather.
Scope of these two materials also have some differences, in terms of footwear, PVC leather is used in the lining or bear the weight of parts, or the manufacture of shoes; PU leather footwear can be applied to fabric or to bear the weight of the parts . In the bags, the use of more than a PVC leather, it is because the bag of items different from shoes feet, will not emit heat, do not bear a person's weight. PU leather and PVC leather relatively easy to distinguish, from the corner to see, PU base fabric than many thick PVC, also feel a difference, PU feel softer, PVC Some feel hard; can also be used to identify fire, PU taste the taste than PVC to light a lot.
