Comparison of Properties of PU Synthetic Leather and PVC Artificial Leather

According to the classification of raw materials, Artificial leather can be roughly divided into Pvc Artificial Leather and Pu Synthetic Leather. PVC artificial leather is an imitation leather product with textile or knitted material as the base and polyvinyl chloride resin as the coating. The main purpose is to make the appearance into a material similar to Natural Leather. Its characteristics are similar to natural leather, with bright appearance, abrasion resistance, folding resistance, acid and alkali resistance, etc. But there are also defects such as hard hand feeling, poor leather, poor comfort, poor aging resistance, heavy odor, and easy migration and precipitation of plasticizers. In addition, from the perspective of environmental protection, during the production process of PVC, highly toxic dioxins will be produced and released. The toxic additives in PVC products will pollute the environment, and enter the human body with certain carcinogenic effects. The problem of PVC garbage disposal is more difficult. Whether it is burned or buried, it will produce and release dioxins and chlorinated compounds that cause land and water pollution, and the recycling of PVC is very difficult. PVC artificial leather will gradually be eliminated.

PU Synthetic Leather is used on artificial leather instead of PVC. Polyurethane is the abbreviation of polyurethane formate. It is a general term for polymer compounds formed by the action of binary or polyisocyanates and binary or polyhydroxy compounds. It is a new organic polymer material with the following excellent characteristics: , High strength, thin and elastic, soft and smooth, good air and water permeability, and waterproof; 2. It still has good tensile strength and flexural strength at low temperature, and has good light aging resistance and hydrolysis resistance stability ; 3. Flexible and wear-resistant, appearance and performance are close to natural leather, easy to wash and decontaminate, easy to sew; 4. Smooth and compact surface, can be used for a variety of surface treatments and dyeing, variety.
