  • the present invention relates to a gas generating agent for an airbag.
  • the gas generator is ignited and burned instantly after the collision is sensed by electrical or mechanical ignition, generating gas and inflating the bag.
  • the gas generating agent is usually used in the form of a pellet or a disk. It is essential that such a gas generating agent has an appropriate burning rate. If the combustion speed is low, the bag does not inflate instantly and does not serve as an airbag.
  • gas generating agents are made of powdered raw materials and have impact ignitability. Impact ignitability refers to the ignition sensitivity to impact.If it is too sharp, it can be used in manufacturing processes such as mixing operations and molding processes. The explosion risk of the air becomes large, which is not desirable for safety. Therefore, it is desirable that impact ignitability be as low as possible.
  • the gas generating agent does not have a very high combustion temperature. This is because airbags usually release gas inside after inflation and then contract to absorb the impact of an occupant's crash and help the occupant escape, but when the combustion temperature is high, it is released. The higher the gas temperature, the greater the risk of occupant burns, reduced functionality due to perforations in the bag, and burning of the bag causing a vehicle fire.
