Polyurethane foams are widely used. Soft foam is mainly used for various mats and soundproofing materials of furniture and vehicles; rigid foam is mainly used for heat insulation of household appliances, wall insulation, waterproof spray foam, pipe insulation materials, building plates, refrigerated trucks and cold storage. Insulation materials, etc.; semi-rigid foam for automotive dashboards, steering wheels, etc. There are various types of foam composites (two-component premixes) available on the market, mainly used for (cold curing) high resilience foams, semi-rigid foams, casting and spray hard foams.
Polyurethane elastomers have high elasticity and strength, excellent wear resistance, oil resistance, fatigue resistance and vibration resistance in a wide range of hardness, and are known as "wear rubber". Polyurethane elastomers have a small output in polyurethane products, but polyurethane elastomers have excellent comprehensive properties and have been widely used in metallurgy, petroleum, automotive, mineral processing, water conservancy, textile, printing, medical, sports, food processing, construction and other industrial sectors. .
PU is polyurethane, and PU skin is the skin of polyurethane. Garment manufacturers use this material to produce garments, commonly known as imitation leather garments. PU is the abbreviation of English polyurethane, the quality of chemical Chinese name polyurethane is also good or bad, good bags are mostly imported PU leather
The 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. Because of its unique craftsmanship, stable quality and novel varieties, it is recognized by consumers as 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.
