PU is the abbreviation of polyurethane, and the Chinese name is polyurethane for polyurethane. Because only a simple modification of the formula is required, different physical properties such as density, elasticity, and rigidity can be obtained. At present, a large number of glass fiber insulation materials, wood, and traditional rubber products have been replaced.

What you are talking about is actually synthetic PU leather, which is a kind of artificial leather.

Polyurethane, abbreviated as PU (Polyurethane) Polyurethane is the abbreviation of polyurethane, which is based on isocyanate (material A) and polyether polyol (material B) as the main raw materials, and then with a small amount of other additives and auxiliary materials (foaming agents, catalysts, flame retardants, etc.) through high-speed stirring and mixing, in a fixed container reaction to form a continuous foaming polymer. According to the different raw materials and formulas used, it can be made into two types: solid and expanded foam, and the foamed can be made into soft, semi-rigid and rigid and special foam plastics. At present, rigid polyurethane foam is mostly used in the insulation of building walls.

There are two types of rigid foams: polyurethane foam PUR and polyisocyanurate foam PIR.

For PU leather.

pu is in English.

The abbreviation of Poly Urethane, the Chinese name of Bai chemical "polyurethane" du.

PU leather is the epidermis of polyurethane components. Now DAO is widely used in the decoration of bags, clothing, shoes, vehicles and furniture, it has been increasingly affirmed by the market, its wide range of applications, the number of large quantities, the variety of many varieties, is the traditional natural leather can not be satisfied.

The quality of PU leather is also good or bad, and good PU leather is even more expensive than genuine leather, and the shaping effect is good and the surface is bright.

In China, people are accustomed to calling the artificial leather produced with PU resin as raw material as PU artificial leather, and the artificial leather produced with PU resin and non-woven fabric as raw materials is called PU synthetic leather (referred to as synthetic leather). It is customary to refer to the above three types of leather collectively as synthetic leather.

Explain that the fabric is leather, not leather.

PU is the abbreviation of English poly urethane, and the chemical Chinese name is "polyurethane". PU leather is made of polyurethane.

of the epidermis. Now widely used in luggage, clothing, shoes, vehicles and furniture decoration, it has been increasingly affirmed by the market, its wide range of applications, the number of large, the variety of many, is the traditional natural leather can not be satisfied. The quality of PU leather is also good or bad, and good PU leather is even more expensive than genuine leather, and the shaping effect is good and the surface is bright.

Cleaning Method:1Wet with water and detergent cleaning, avoid gasoline scrubbing;

2.Cannot be dry cleaned;

3.It can only be washed with water, and the washing temperature cannot exceed 40 degrees;

4.Cannot be exposed to sunlight;

5.Do not come into contact with some organic solvents;

Leather jackets need to be hung and bagged for storage, and cannot be folded.

PU: Polyurethane coatings are selected for their excellent wear resistance and weather resistance. Rigid foam with light weight and good abrasion resistance is used as the core material for skis and surfboards, and polyurethane elastomers with excellent elasticity and abrasion resistance are used as soles for sneakers.

PU is polyurethane, and PU skin is the epidermis of polyurethane components. Now garment manufacturers widely use this material to produce clothing, commonly known as imitation leather clothing.

Its quality is also good or bad, and good bags are mostly imported PU skin; PU leather is generally the second layer of leather on the reverse side of cowhide, and a layer of PU resin is coated on the surface, so it is also called film cowhide. It is cheaper and has a high utilization rate. With the change of technology, it is also made of various grades of varieties, such as imported two-layer cowhide, because of the unique process, stable quality, novel varieties and other characteristics, for the current high-grade leather, ** and grade are not inferior to the first layer of leather.

PU leather and leather bags have their own characteristics, PU leather bags have beautiful appearance, easy to take care of, **low, but not wear-resistant, easy to break; Genuine leather** is expensive and cumbersome to care for, but durable.

PU (Chinese name: polyurethane).

The properties, uses, and classifications of PU materials are very complete.

Other information big brothers and sisters have said, I am a polymer, I tell you a little bit about the nature of polyurethane you have from what you said about hard thermosetting: thermosetting is to make it molded in the heating process (that is, to make it into what you want), basically belongs to a molding and one use, not as good as PE, PET, PP (thermoplastics), PU is difficult to use, it can be said that the ** point is basically not charged, because most of them are used in thermoforming, and the cost is high for them, difficult.

It's not completely useless: the polyurethane material itself has the effect of sound insulation, shock absorption and heat insulation, which can be used for packaging and transportation or used for building heat and sound insulation, and the effect must be very good!!

As for**on Alibaba** and buyers!

The Chinese name of pu is polyurethane, and there are more toys, and the new material is more than 20,000 tons.

The piece of stuff you said is easy to make with hard PU, and the raw materials are added at more than 20,000 per ton. I want to buy a PU machine to do it. I know better.

Artificial leather is a plastic product that looks and feels like leather and can be used in place of it. It is usually made of fabric, coated with synthetic resin and various plastic additives.

Classification by synthetic resins used.

1 PVC artificial leather.

It is a mixture of polyvinyl chloride resin, plasticized type and other compounding agents, coated or laminated on the fabric, and made by a certain processing process. In addition, there are double-sided PVC artificial leather with a plastic layer on both sides of the substrate.

2 Polyamide artificial leather.

It is a plastic product with a continuous cell structure made by the method of nylon 6 or nylon 66 solution slowly coated on the fabric and film.

3 Polyolefin artificial leather.

Polyethylene artificial leather is a kind of foam artificial leather, which is made of low-density polyethylene resin as the main raw material, mixed with modified resin, cross-linking agent, lubricant, foaming agent and other components.

4 Polyurethane artificial leather.

Polyurethane artificial leather is further divided into dry polyurethane artificial leather and wet polyurethane artificial leather. The so-called dry polyurethane artificial leather refers to a multi-layer structure composed of a multi-layer film and a base cloth after the solvent is volatilized from the solution of solvent-based polyurethane resin. The wet polyurethane artificial leather is a multi-layer structure with good air permeability and moisture permeability, and a continuous porous layer obtained by using the water-based polyurethane resin and water film-forming method.
