Pu material how do you know

PU is an abbreviation of Polyurethane, and the Chinese name is polyurethane referred to as polyurethane. Pu material is widely used in many industries. Since only simple modification of the formula is required, different physical properties such as density, elasticity, and rigidity can be obtained. At present, it has largely replaced glass fiber insulation materials, wood, and traditional rubber products. Then, the next small series for everyone to introduce pu material how.

How about pu material

PU, namely polyurethane, is abbreviated as polyurethane. It is a macromolecular compound containing a -NHCOO- unit in the molecular structure. This unit is formed by a mixed reaction of an isocyanate group and a hydroxyl group. The characteristics of pu material are obvious, which is also the key to achieving a broad market. In the home improvement industry, it is generally used in the production of living room sofas and other skins.

PU, also known as recycled leather, recycled leather. It is characterized by light weight, abrasion resistance, non-slip, cold resistance and chemical resistance, but it is expensive, easy to tear, poor in mechanical strength, and poor in tear strength. PU color less. The main color is black or brown.

Soft texture, suitable for making casual bags or furniture skins, the price is not high, easy to decolorize.

PU fabrics are simulated leather fabrics made of synthetic materials with a genuine leather texture that are extremely durable and inexpensive. People often say that the PU leather is a leather material, such as PVC leather, Italian leather paper, recycled leather and so on. The manufacturing process is slightly more complicated, because PU's bottom fabric tensile strength is good, in addition to coating on the bottom On the cloth, it is also possible to include the base cloth so that the outside of the base cloth does not exist.

PU material production process advantages

1, can be cured in a few seconds, improve efficiency can greatly save the cost, is the most cost-effective;

2, completely reflect the original outline of the external shape and specific details;

3, the color can be adjusted according to the requirements;

5, 100% solids content, no organic solvent;

6, excellent waterproof and anti-fouling ability to facilitate cleaning and maintenance;

7, very light weight, easy to handle, storage, collection;

8, EPS substrate does not require any treatment, no false mesh or brush with a viscous primer;
