Brother: Do you know the formula of PU? What is the unit of measurement for the mass content of PU p

PU material ** business reminds you that the master of the pipe ingredients should hit **.

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!

PU is the abbreviation of polyurethane material, and your material is called polyurethane rigid foam, referred to as rigid foam, which is used for decoration, heat preservation, heat insulation and other applications. The market price of polyurethane rigid foam raw materials is now 12,000-13,000 yuan, and different colors, densities, hardness, etc. can be adjusted according to different special requirements.

PU is polyurethane, about 15,000-20,000 more, depending on the specific model.

Do you want the formula of PU potting compound, you can do formula analysis here and restore the specific formula composition.

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, traditional rubber products have been replaced.

Polyurethane soles offer a number of advantages: low density, soft texture, comfortable and lightweight to wear; Good dimensional stability and long storage life; Excellent abrasion resistance and flexural resistance; Excellent shock absorption and anti-slip performance; Good temperature resistance; Good chemical resistance and much more. Polyurethane is mostly used in the manufacture of high-end leather shoes, sports shoes, travel shoes, etc.

PU leather is also a kind of synthetic leather, and most of the materials of sneakers are made of PU, and some fashions will also be used. Good PU feels soft, wear-resistant, non-fading, waterproof, and daily care is simpler than genuine leather products.

PU is leather products to put it bluntly

weight ratio; Or the laboratory commonly uses grams, and the production ingredients are measured in kilograms.

The measurement and ratio of PU formula is just a personal habit.
