To know what is water-based PU synthetic leather, you must first know the classification and structure of synthetic leather.

PU synthetic leather is divided into dry PU leather and wet PU leather. Dry PU leather is composed of four layers of base cloth, adhesive layer, surface layer and surface treatment layer, while wet PU leather is composed of five layers of base cloth, adhesive layer, foam layer, surface layer and surface treatment layer. Structural composition, wet PU leather has one more foam layer than dry PU leather. The adhesive layer, foam layer, surface layer and surface treatment layer of traditional solvent-based PU leather are all made of polyurethane (ie PU) chemical materials containing toxic solvents such as DMF. The water-based PU leather is made of water-based polyurethane as raw material and water instead of toxic solvents such as DMF. On the surface, DMF and other solvents in chemical materials are replaced with water, but from the perspective of scientific research, qualitative changes have taken place in many aspects such as raw material selection, patent formula, technological process, and equipment selection. Change.

Compared with the traditional solvent-based PU leather on the market, the water-based PU leather is harmless to the body, non-toxic and odorless. It also reduces the energy consumption in the production process, and has no toxic and harmful waste gas and waste water discharge. Therefore, it can fully meet the highest requirements for environmental protection of synthetic leather at home and abroad. Water-based PU leather also has excellent physical properties, with high peeling, high folding resistance, high wear resistance, etc., and is the best substitute for genuine leather and traditional solvent-based synthetic leather. Designated leather for developed countries such as Europe, America and Japan.
