The difference between PVC and PU

Most people will refer the PVC, PU leather or imitation leather collectively as artificial leather . PVC, PU are PVC (plastic one), but two products of manufacturing processes are different.

PVC leather in the manufacturing process must first melt the plastic particles mixed into a paste, evenly coating thickness required in the T / C knitted fabric substrate, and then into the foaming furnace for foaming, it has to adapt to production of different products and different requirements of flexibility, while the baked surface treatment (dyeing, embossed, polished, extinction, grinding fluff, are mainly in accordance with specific requirements for the product).

PU leather in the manufacturing process more complex than the PVC leather, because PU good tensile strength of the bottom fabric is canvas PU material, which can be coated on top of the base fabric, but also can be included in the middle of the bottom cloth, so that the outside fabric of existence is not in the end. The physical properties of PU leather PVC leather than good, winding resistance, good flexibility, tensile strength, with permeability (PVC-free). PVC leather tread pattern through steel hot roll formed; PU leather with a pattern paper pattern is the first hot pressing is in the semi-finished leather surface, waiting for cooling down after the separation of paper to leather, so the surface treatment. PU leather PVC leather prices more than twice as high in some special requirements of PU leather PVC leather than the price 2-3 times higher. PU leather needed for the general pattern of paper can only use 4-5 times will come to end of life; pattern roll long life cycle, so the cost of PU leather PVC leather than high.

PU, PVC of different ways easier to see from the corner of the end of PU thick PVC fabric than many, also has different feel, PU soft touch, some of; PVC hard some of the handle; also use fire to burn, PU's taste than the smell of PVC to light a lot.

PU's feeling better, soft, relatively high cost .. PVC feel bad, (even if also feel dry soft soft), and low cost.



PU bag, many people called Leather package, something like this PU leather material. However, much cheaper off than leather bag, so many are using this PU material bag.



PVC bag, relatively smooth surface, texture similar package than PU. Generally low-cost bag to use this material, it is also much cheaper than the PU material.
