Propellants for automotive applications: micro gas generators and actuators
Active and passive car safety systems continue to evolve. The seat belt pretensioner, as a passive system, tightens the seat belt in case of an accident. Many pretensioners are equipped with nitrocellulose based propellants from Nitrochemie. These propellants have proven themselves extremely reliable for decades.
The passive pedestrian protection in the form of raising the hood works with an actuator installed in the engine compartment. Nitrochemie supplies polymer-bonded propellants to leading actuator producers.
