The full English name of PU is urethane, and the chemical Chinese name is polyurethane, also known as microfiber leather (full name is "microfiber reinforced PU leather").

It has extremely excellent wear resistance, excellent cold resistance, air permeability and aging resistance. It is one of the important materials of sofa and other furniture and has the characteristics of modern style. Due to the influence of the Animal Protection Association and the development of technology, the performance and application of polyurethane synthetic leather exceed that of natural leather. After adding microfiber, the toughness, air permeability and abrasion resistance of polyurethane are further strengthened. There is no doubt that the performance of such finished products is quite excellent. Because of the unique technology, stable quality, novel varieties and other characteristics, it can be called one of the current high-grade leather, and the price and grade are no less than the first layer of leather.
