tpu (ThermoplasticPolyurethane) air bag material is a kind of high performance polyurethane elastomer, due to its excellent properties and wide application, has become the mainstream in airbag industry material. The following are the advantages and disadvantages of TPU airbag material.


1. High strength: TPU airbag material has very high strength and toughness, and can resist various external shocks, so as to protect passengers and vehicles.

2. Good wear resistance: TPU airbag material has excellent wear resistance, can withstand multiple friction and wear, to ensure the long-term reliability of the airbag.

3. High temperature resistance: tpu air bag material has a high melting point and glass conversion temperature, can withstand high temperature environment, to ensure the normal operation of the air bag in the high temperature environment of the car.

4. Chemical corrosion resistance: TPU airbag material can withstand the corrosion of a variety of chemical substances, to ensure the reliability of the airbag in various extreme environments.

5. Easy to process: TPU airbag materials can be processed by hot forming, extrusion, injection molding and other processes, making the production process more simple and efficient.


1. Easy aging: The aging phenomenon of TPU airbag material is serious, which will lead to the deterioration of material performance, so it is necessary to take some anti-aging measures.

2. High cost: The production cost of TPU airbag material is relatively high, which leads to its relatively high selling price and high use cost.

To sum up, TPU airbag material has many advantages, such as high strength, good wear resistance, high temperature resistance, chemical corrosion resistance and easy processing, but it also has some disadvantages, such as easy aging and high cost. However, TPU airbag material is still one of the mainstream materials in the airbag industry, because of its excellent performance can effectively protect the safety of vehicles and passengers.
