Average person can put the synthetic leather beyond dermis if: PVC, PU leather is called collectively man-made leather or copy leather.PVC, PU is polyvinyl chloride (plastic), but the two products are not the same manufacturing process.
PVC leather in the process of manufacturing plastic particles melt mixing into a paste, in accordance with the provisions, the thickness of the uniform coating on T/C knitted fabric bottom base, and then into the foam foaming furnace, make its have can adapt to produce all kinds of different products and different requirements of flexibility, while out for surface treatment (dyeing, embossing, extinction, grinding surface polishing, burr, etc., mainly in accordance with the specific product requirements for).
PU leather is more complicated than PVC leather in manufacturing process. As the PU substrate is canvas PU with good tensile strength, it can be coated on the substrate and included in the middle, so that the existence of the substrate cannot be seen.The physical property of PU leather is better than that of PVC leather, which has good resistance to twists and turns, good softness, great tensile strength and air permeability (PVC has none).PVC leather pattern is through the steel pattern roll hot press;The pattern of PU leather is to use a kind of patterned paper to heat stick and press on the surface of semi-finished leather, wait for cooling down before separating the paper leather and making surface treatment.The price of PU leather is more than double that of PVC leather, and the price of PU leather with special requirements is 2-3 times higher than that of PVC leather.The decorative paper needed by general PU leather can only be scrapped after 4-5 times.The service cycle of pattern roller is long, so the cost of PU leather is higher than that of PVC leather.
The difference between PU and PVC is relatively easy. The back cloth of PU is much thicker than that of PVC.The feel of PVC is harder;Also can use fire to burn, PU flavor than PVC flavor is much lighter.
