What are the differences between PVC artificial leather and PU artificial leather?

What are the differences between PVC artificial leather and PU artificial leather? PU stands for polyurethane and PVC is the abbreviation of polyvinyl chloride. People are accustomed to referring to artificial leather produced from PVC resin as PVC artificial leather (abbreviated as artificial leather). Artificial leather produced from PU resin is called PU artificial leather (referred to as PU leather for short); artificial leather produced from PU resin and non-woven fabric is called PU synthetic leather (referred to as synthetic leather for short).

The differences between PU artificial leather and PVC artificial leather:

PU leather is less toxic and more environmentally friendly than PVC leather (environmentally friendly leather mostly refers to PU leather), and it feels softer than PVC leather.

If placed in a poor environment for a long time, it may crack (hydrolyze), but precisely because of this, it will not cause secondary pollution to the environment. When the product is discarded, it can naturally degrade, while PVC will not decompose for thousands of years.

The base of PVC artificial leather is generally looser, while the base of PU synthetic leather is usually denser.

All PVC artificial leather has a foamed layer, while PU is a mixture of pulp and fabric base.

PU artificial leather, anti-yellowing agent, yellowing resistance up to grade 4 standard.

PVC leather is more durable, tear-resistant, scratch-resistant, flame-retardant and weather-resistant than PU leather.
