PU is polyurethane, and PU skin is the skin of polyurethane. Nowadays, garment manufacturers use this material extensively to produce garments, commonly known as imitation leather garments. PU is the abbreviation of English ploy urethane, the name of the chemical Chinese polyurethane is also good or bad, and the good bag is mostly imported PU leather;
PU leather is a second layer of leather which is generally cowhide on the reverse side. It is coated with a layer of PU resin on the surface, so it is also called film cowhide.
Its price is cheaper and its utilization rate is high. With the change of the process, it is also made into various grades, such as imported two-layer cowhide. Due to its unique craftsmanship, stable quality and novel varieties, it is the current high-grade leather, and its price and grade are no less than the top layer of leather.
PU leather and leather bag have their own characteristics, PU leather bag looks beautiful, good care, low price, but not wearable, easy to break; leather is expensive, troublesome, but durable.
The full name of the ultra-fine leather is "microfiber reinforced PU leather". He has excellent wear resistance, excellent cold resistance, breathability and aging resistance.
PU is a polyurethane. Polyurethane leather has excellent properties. In this respect, Bayer, BASF, and Huntsman's production capacity are world-class, while textile fiber suppliers represented by Toray and Asahi have higher product technologies.
In foreign countries, due to the influence of animal protection associations and the development of technology, the performance and application of polyurethane synthetic leather exceeds that of natural leather.
After the addition of the ultrafine fibers, the toughness, gas permeability and wear resistance of the polyurethane are further enhanced. There is no doubt that such a finished product is quite excellent in performance.
Leather relates to the structure of leather articles, and in particular to their surface coverings.
Because it is plated on the inner surface of leather or leather products, or on the outer surface, or on the inner and outer surfaces. It can not only beautify but also reflect infrared rays, which greatly improves the thermal insulation performance or thermal insulation performance of leather. It does not fade, wear, and maximizes the breathability and moisture permeability of the leather itself.
