On Tuesday, a group of members of the US Congress hearing, an executive of Japan's Takata company said it would immediately reduce recall airbag volatile chemicals production.
This chemical is called ammonium nitrate, in the case of an accident, it is used to open the airbag propellant. But now it has been implicated in the global recall of 53 million vehicles, the car's airbag Takada were flawed. In the US alone, there are nearly 3,400 million units recall problem cars. Kevin Kennedy, executive vice president of a subsidiary of TK Holdings, said Takada, ammonium nitrate seems to be causing the inflator to premature rupture of one of the factors, the inflator to put too much pressure ejected at high speed when the metal debris. The defect has resulted in six deaths and more than one hundred people were injured.
Takada now guanidine nitrate used as a backup propellant. Kevin Kennedy before the House subcommittee, said: "We started production in a year or two, we will continue to promote the use of guanidine nitrate, and ammonium nitrate production will be cut immediately." Takata is the only use of ammonium nitrate as an airbag propellant Manufacturers, company executives said they will continue to use ammonium nitrate, but the new program will be more secure in the wet zone. Kennedy added that the use of ammonium nitrate in the old section of the inflator has been used as replacements for recalled vehicles use - but these vehicles are likely to be the second recall for repair.
