PU and PVC some of the differences, and divide it

Most people would like synthetic leather than leather: PVC, PU leather or imitation leather collectively. PVC, PU are PVC (plastic in one), but the two products of the manufacturing process is not the same.

     PVC leather in the manufacturing process of the plastic particles melt first mixed into a paste, the required coating thickness uniformity in the T / C knitted fabric substrate, and then into the foaming foaming furnace, it has to adapt to production of different products and different softness required, while the baked surface treatment (dyeing, embossing, polishing, matting, grinding fluff, 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 as good tensile strength canvas PU material, in addition to the base fabric coated on the top, the bottom cloth can also be included in the middle, so that not in the end the outside cloth existence. PU leather, PVC leather than the physical properties and good resistance to twists and turns, good flexibility, tensile strength, gas-permeable (PVC free). PVC leather pattern is the pattern roll through the hot steel made​​; PU leather pattern is made of a floral paper first heat pressure in the semi-finished leather surface, waiting for the paper to cool before the separation of leather, making the surface treatment. PU leather, PVC leather than the price to be higher than doubled, some special requirements, PU PVC leather than the price to be 2-3 times higher. PU leather pattern paper required shall only be used 4-5 times scrapped; tread rolls long life cycle, so PU leather, PVC leather than the cost is high.( shoes manufacturer

     The scope of these two materials also have some differences. In terms of footwear, PVC leather lining is used in non-weight-bearing parts, or manufacturing children's shoes; PU leather for shoes can withstand the weight of the fabric or the site. In the bag, the more is applied PVC leather. This is because the article is different from the bag to wear the foot in the shoe, do not emit heat; do not bear the individual's body weight. shoes factory

     PU, PVC difference method is relatively easy to see from the corner of the base fabric PU much thicker than PVC, also feel a difference, PU feel softer; PVC hard some of the texture; also use fire to burn, PU's to taste the taste than PVC much lighter. women shoes manufacturer
