During the manufacturing process of PVC leather, plastic particles must be hot-melted and stirred into a paste, and then evenly coated on the T/C knitted fabric base according to the specified thickness, and then entered into a foaming furnace for foaming to make it It has the softness to adapt to the production of various products and different requirements, and it can be surface treated at the same time as it comes out of the oven.
The manufacturing process of PU leather is more complicated than that of PVC leather. Since the base fabric of PU is canvas PU material with good tensile strength, in addition to being coated on the base fabric, The base fabric can be included in the middle so that the existence of the base fabric cannot be seen from the outside. The physical properties of PU leather are better than PVC leather, including resistance to bending, good softness, high tensile strength, and breathability.
The pattern of PVC leather is hot-pressed by a steel pattern roller; the pattern of PU leather is hot-pressed on the surface of the semi-finished leather with a pattern paper, and then it is processed after it cools down. Separation of paper leather and surface treatment.
The price of PU leather is more than double that of PVC leather. The price of PU leather with certain special requirements is 2-3 times higher than that of PVC leather. Generally, the pattern paper required for PU leather can only be used 4-5 times before being scrapped; the pattern roller has a long service life, so the cost of PU leather is higher than that of PVC leather.
The waterproofing effect of PU coating and PVC coating depends on different uses, so it is not certain which one is better. The thickness of the waterproof coating is determined based on different uses.
