Most people will, such as synthetic leather than leather: PVC, PU leather or imitation leather collectively referred to as artificial leather. PVC, PU are PVC (plastic one), but the two products, manufacturing processes are not identical.
PVC leather in the manufacturing process first melt the plastic particles mixed into a paste, the required coating thickness uniformity in the T / C knitted fabric substrate, and then into the furnace for foaming foam, it has to adapt production of different products, different requirements of flexibility, while the baked surface treatment (dyeing, embossing, polishing, matting, fluff grinding, etc., mainly in accordance with specific requirements for the product).
PU leather in the manufacturing process more complicated than the PVC leather, PU's as good tensile strength canvas base fabric is PU material, in addition to coating the top of the base fabric, the fabric can also be included in the middle of the bottom, so that the outside cloth is not in the end there. PU leather, PVC leather than the physical properties and good resistance to twists and turns, good flexibility, tensile strength, and with ventilation (PVC free). PVC leather pattern is the pattern of steel hot roll formed; PU leather pattern is the paper with a pattern in the first semi-finished leather hot sticking surface, waiting for cooling down after the separation of the paper leather, making the surface deal with. PU leather, PVC leather than the price more than twice as high in some special requirements of PU leather than the price of PVC leather to be 2-3 times higher. PU leather is generally required for pattern paper can only be used 4-5 times shall scrapped; pattern roller with a long cycle, so the cost of PU leather for high than PVC leather.
The scope of these two materials are also quite different. In terms of footwear, PVC leather lining is used in the site or to bear weight, or manufacture of children's shoes; PU leather for shoes can withstand the weight of the fabric or the site. In the bag, the more applicable is the PVC leather. This is because the items in the bag is different from the shoes to wear in the feet, will not emit heat; do not bear the weight of the individual.
PU, PVC's way easier to distinguish, from the corner to see the end of PU PVC fabric thickness than many, also feel a difference, PU's soft to the touch of some; PVC hard some of the feel; can also use fire to burn, PU's taste the taste than to light a lot of PVC
