Polyurethane（ PU ）The product is a kind of macromolecular material. Its material structure contains polyols and multifunctional isocyanates, which are made by reaction. Polyurethane products have the characteristics of high strength, abrasion resistance, durability, oil resistance, chemical corrosion resistance, etc., so they are widely used in many fields such as automobiles, aviation, construction, footwear, agricultural machinery, etc.

1、 Application of polyurethane products in automobile industry

Polyurethane products are mainly used in automobile seats, steering wheels, door trim panels, braking systems, shock absorbers, suspension systems, tires, etc. Polyurethane products can not only improve the comfort and safety of vehicles, but also reduce the quality of vehicles, improve fuel economy and reduce emissions.

Polyurethane car seats have the characteristics of soft and hard suitability, high comfort, good impact resistance, strong durability, and are widely used in luxury cars, business cars and other high-end models. The polyurethane tire has the characteristics of lightweight, reducing rolling resistance, improving grip, reducing noise and so on, and has been used in racing cars, fighter planes and other fields.

2、 Application of polyurethane products in aerospace field

Polyurethane products are widely used in the aerospace field, mainly in aircraft, missiles, satellites and other aspects. Polyurethane products have the characteristics of light weight, high strength, high rigidity and high durability, which can meet various requirements of aircraft, reduce the mass of aircraft, and improve the airborne capability and flight performance.

Polyurethane aircraft braking system is an important application field of polyurethane products in the aviation field. The high strength and wear resistance of polyurethane make it an ideal material for brake pads, which can ensure that the aircraft has sufficient strength and reliability during high-speed takeoff and landing.

3、 Application of polyurethane products in construction industry

Polyurethane products are widely used in the field of construction industry, mainly in thermal insulation materials, thermal insulation materials, waterproof materials, etc. As an excellent thermal insulation material, polyurethane has the advantages of good heat insulation, moisture resistance, fire resistance and easy construction. Therefore, it is widely used in building external wall insulation, roof insulation and air conditioning pipe insulation.

Polyurethane also has unique advantages in building waterproof materials. It has good tightness, can resist external forces and is not easy to rust and corrosion; At the same time, it has excellent weather resistance, which can keep the building intact when exposed to wind and rain for a long time.

4、 Application of polyurethane products in the field of shoe materials

Polyurethane products are used as sole materials in the field of shoe materials. At present, the process of polyurethane soles has been relatively mature, and it has good wear resistance, strength, toughness and comfort. It is one of the most popular materials in the modern shoe material market.

The advantage of polyurethane soles is that they will not cause harmful effects on the human body, but also meet people's needs for soles. The shoes with polyurethane soles are generally lightweight, with optimized structure and good stability, which can give people a sense of lightness. In addition, the polyurethane soles have very good recovery performance and are not easy to deform, which is particularly obvious in the field of sports shoes.

5、 Application of polyurethane products in agricultural machinery field

Polyurethane products are mostly used in the field of agricultural machinery, and their main function is to improve the traction and wear resistance of tractors.

Compared with automobile tires, polyurethane agricultural machinery tires have to withstand greater impact and load, so they have higher requirements on the strength and durability of materials. For this reason, polyurethane tire manufacturers generally use materials with compact structure to ensure their strength and durability.

In general, with the increasing demand for high-performance materials from all walks of life, polyurethane products have been used more and more widely. It is believed that its application field will continue to expand in the future, bringing more convenience and benefits to people.
