Synthetic leather is generally divided into:

The first is PVC (polyvinyl chloride), which burns to produce water, carbon dioxide, chlorinated compounds, and even chlorine gas; It is a mixture of polyvinyl chloride resin, plasticizer and other matching agents, coated or glued to the fabric, after a certain processing process and made of wake up products. In addition, there are double sided PVC artificial leather with plastic layers on both sides of the substrate.

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

The third, and most common, is PU leather, which, when fully burned, produces water, carbon dioxide, nitrogen, and small amounts of nitrogen-containing compounds. Polyurethane artificial leather is divided into dry polyurethane artificial leather and wet polyurethane artificial leather. The so-called dry polyurethane artificial leather refers to the solvent based polyurethane resin solution volatilized off the solvent, the multilayer film and the substrate formed by the multilayer structure. The wet polyurethane artificial leather is a multi-layer structure with good air permeability and moisture permeability, and a continuous porous layer, which is made of solvent-based polyurethane resin and water film forming method.

Artificial leather can be divided into many types because of the different synthetic resin used in artificial leather, different types of base materials, different production methods, whether there is foaming and different uses. Now artificial leather by the use of synthetic resin, production technology and use of classification.
