Lanxess Bayoxide® E AB 21 γ-Fe2O3
Categories:	Ceramic; Oxide; Other Engineering Material; Additive/Filler for Polymer
Material Notes:	CAS No: 1309-37-1. Bayoxide® E AB 21 is a technical iron oxide used in conventional gas-generation airbag systems where it serves as an oxidizing agent and for scorification of the sodium formed in the gas-generating reaction. Thereby, a controlled unfolding of the airbag can be ensured. The requirements placed on the iron oxide used in this critical safety application are high. Bayoxide® E AB 21 has a low heavy metal content, neutral to slightly alkaline pH and excellent free flowing properties. Information provided by Lanxess.
