Polyurethane (Polyurethane, PU) is an organic polymer compound widely used in the field of chemical production raw materials. It has excellent physical properties, chemical stability and processing performance, so it is widely used in various fields, such as construction, furniture, automobiles, electronics, textiles, etc. This article will detail the properties and uses of polyurethane.

1. the properties of polyurethane

1. physical properties
polyurethane has high strength, high hardness, high elasticity, wear resistance, oil resistance, corrosion resistance and other excellent physical properties. Its hardness can range from soft to hard, with good impact resistance and shock absorption performance.
2. Chemical stability
polyurethane has good chemical stability, can resist the corrosion of acid, alkali, salt and other chemicals, and also has good stability in many organic solvents.
3. processing performance
polyurethane has good processing performance, and can be made into various shapes and sizes of products by injection molding, extrusion, calendering, blow molding and other processing methods.

2. polyurethane use

1.
polyurethane in the field of construction has a wide range of applications in the field of construction, mainly used as insulation materials and waterproof materials. Polyurethane thermal insulation material has high thermal insulation performance, which can reduce energy consumption and environmental pollution. At the same time, polyurethane waterproof material also has good waterproof performance, which can extend the service life of the building.
2.
in the field of furniture Polyurethane is mainly used as a filling material for upholstered furniture in the field of furniture, such as sofas, mattresses, etc. Polyurethane upholstered furniture has the characteristics of comfort, durability and easy cleaning, and is deeply loved by consumers.
3. Automotive field
Polyurethane has a wide range of applications in the automotive field, mainly used as automotive interior and exterior materials. Automotive interior materials need to have the characteristics of comfort, safety and environmental protection, and polyurethane materials can meet these requirements. At the same time, polyurethane can also be used to manufacture automobile tires to improve the wear resistance and impact resistance of tires.
4.
in the field of electronics Polyurethane is also widely used in the field of electronics, mainly used as insulating materials and protective materials for electronic components. Polyurethane insulating materials have excellent electrical properties and heat resistance, which can ensure the normal operation of electronic components. At the same time, polyurethane protective material also has good impact resistance and abrasion resistance, which can protect electronic components from external damage.

In short, polyurethane as an excellent chemical production raw materials, in various fields have a wide range of applications. With the continuous progress of science and technology and the continuous improvement of people's quality of life requirements, the application prospects of polyurethane will be more broad.
