With the continuous improvement of domestic and international technology and the continuous innovation of process technology, artificial leather products have developed into daily consumer products. PVC artificial leather, which occupies a dominant position, is gradually being replaced by high-tech, high-grade PU leather. So what are the important factors for PU leather to replace PVC artificial leather?
First, let's understand PVC artificial leather. PVC artificial leather is mainly made by adding plasticizers and stabilizers to PVC, and then coloring, coating gelation, embossing or embossing to create various products with appearances similar to leather. With its characteristics similar to natural leather, bright appearance, soft texture, wear resistance, folding resistance, acid and alkali resistance, etc., PVC artificial leather has developed a considerable scale since the 1970s.
However, the development of PVC in recent years has been subject to certain restrictions, because the breathability and hygroscopicity of PVC artificial leather are relatively poor, and PU leather can replace PVC wherever it is used.
PU leather is a synthetic leather material made of polyurethane, using pile fabric as the base and polyurethane solution as the coating. PU leather not only has excellent high strength and toughness, but also is resistant to aging, breathable, moisture-permeable, waterproof, and oil-resistant, making it a mature environmentally friendly material. Due to its diverse colors, good material elasticity, and natural texture, it is used in many fields, such as clothing, luggage, shoes, automotive interiors, and sofas.
Complete production chains have been established in many parts of China, and the skilled production technology has greatly reduced the production cost of PU synthetic leather. Among them, water-based polyurethane synthetic leather products, solvent-based synthetic leather, and BPU zero-solvent leather, among which water-based polyurethane synthetic leather products are not only cost-effective but also promote environmental protection; BPU zero-solvent leather does not contain solvents, and its safety, non-toxicity, and excellent physical properties have greatly improved people's trust in synthetic leather materials. It has also laid a solid technical foundation for PU synthetic leather to further replace traditional PVC synthetic leather materials.
