3. Raw Materials
Ideally, airbags should be made of new rubber material that adheres to the following standards:
- ISO34-1 Tear Strength ≥400 N/cm
- ISO37 Tensile Strength ≥18 MPa, Elongation at Break ≥400%
- ISO1761-1 Hardness (Shore A) 60±10°
- ISO815-1 Compression Set
- ISO188 Requirements After Thermal Aging
- ISO1431-1 After Static Ozone Ageing
The keyword here is new.LUHANG NEVER uses recycled or reclaimed rubber material in airbag production. This is a huge red flag. Quality rubber
makes the foundation of the whole “inflatable roller” idea,
especially when it has to bear very high values of weight on top. Recycled and reclaimed rubber have substantially lower elasticity
and has a very fast ageing rate which compromises the integrity of airbags. Use these recycled
rubber airbags a couple of times and you will realise they burst
On the other hand, cords play a big role, too. These “two cords”
are supposed to be two-strand cords with more than 205 N strength
per cord. Some manufacturers, like LUHANG, procure and use a higher
strength cord (above required standard) to ensure quality strength;
but some other suppliers use two-strand cords with lower strength sometimes. There is also the difference with other cords like
dacron cords etc. The difference in use of raw materials can have a
cost difference of more than 65%!!
Raw materials in airbags are sometimes very different from one another, and hard to detect.
