Types of Artificial Leather

According to the classification of synthetic resin used, artificial leather is generally divided into:

The first is PVC (polyvinyl chloride). The products after combustion include water, carbon dioxide, and chlorine-containing compounds, and even chlorine gas; it is a mixture of polyvinyl chloride resin, plasticizers and other compounding agents. It is a wavy product that is covered or attached to the fabric through a certain processing process. In addition, there are also double-sided polyvinyl chloride artificial leathers with plastic layers on both sides of the substrate.

The second type is PE (polyethylene), which theoretically only produces water and carbon dioxide after it is fully burned.

The third and most common one is PU leather (polyurethane). The products after full combustion include water, carbon dioxide, nitrogen, and a small amount of nitrogen-containing compounds. Polyurethane artificial leather is divided into dry-process polyurethane artificial leather and wet-process polyurethane artificial leather. The so-called dry-process polyurethane artificial leather refers to a multilayer structure formed by evaporating the solvent of the solvent-based polyurethane resin solution and adding a base cloth to the multilayer film obtained. The wet-process polyurethane artificial leather is a multi-layer structure with good air permeability and moisture permeability, and a continuous porous layer, which is obtained by using a solvent-based polyurethane resin and an underwater film-forming method.

Due to different synthetic resins used in artificial leather, different types of substrates, different production processes, whether there is foaming and different uses, artificial leather can be divided into many types. The artificial leather is now classified according to the synthetic resin used, the production process and the purpose.
