In the application of automobile manufacturing, polyurethane elastomers are mainly used as key structures such as shock-absorbing buffer blocks. Because elastic polyurethane materials have good cushioning properties, they can be used in combination with high-strength spring devices at the chassis of automobiles to improve shock-absorbing buffer blocks. The effect can also enhance the comfort of the car. Most cars use such materials and technologies. The airbag part is also made of polyurethane material with high elasticity, because this structure is the last barrier to protect the driver and plays an important role. It is required that the strength and elasticity of the airbag must meet the relevant requirements, and elastic polyurethane is the most suitable Choose, and the polyurethane material is relatively light, most airbags are only about 200g.

Tires are an indispensable part of a car. The service life of ordinary rubber tires is relatively short, and they cannot be used in a strong environment, and they also have adverse effects on human health, so better materials need to be selected , and polyurethane materials can meet these requirements, and it also has the characteristics of less investment and relatively simple process. The heat resistance of polyurethane tires is average during sudden braking, which is also the reason for the relatively limited use in specific applications. Generally, polyurethane tires are It is a casting process, which can make the tires adapt to different requirements, so that the tires will not produce pollution and are very green. I hope that in the future, the problem of polyurethane tires not being resistant to high temperatures can be solved, and it can be widely used better.
