TRW Automotive Holdings developed new, greener driver airbag modules, which are made of regenerative plastic material, offering a number of environmental benefits.

The company is the first who managed to create such a module where components, including the airbag cover and retainer plate, are now made from a new, bio-based material. Manuel Poyant, core engineering manager for driver airbags and steering wheel systems at TRW explained that the company is using new bio-based material for its driver airbag modules, which reduces the gases that are released at low levels from new materials, particularly at high temperature. A significant proportion of the carbon in the new plastic material comes from regenerative raw materials, which helps to save fossil resources.

“The plastics sector has evolved significantly in recent years and with the greater focus from the automotive industry on sustainable products and the environment, greener technologies such as bio-materials are high on vehicle manufacturers’ agendas. Our customers are already showing strong interest in this new technology.”

These new driver airbag modules will be ready for production by the middle of 2012 and the company anticipates that the technology could gradually replace all conventional oil based materials in driver airbags in the coming years.
