senior official of Japanese parts maker Takata,
said that the company is still searching for the
main cause of the deadly explosions in its airbags,
Kevin Kennedy executive vice presidents at Takata
's US arm TK holdings told lawmakers that the
company has already focused on the possible
of the main ammonium nittrate propellant in airbag
inflators in certain condition.
US legislators pressed the company on why it
continued to manufacture inflators with the explosive
chimical,arguing that it appears to be the reason why
dozens of Takata airbags have nflated with excessive
force,powering metal shrapnel into drivers and
passengers,leaving at least six dead.
Kennedy said many of the replacements will use
the same chemical,which appears to become unstable
after years of exposure in hot and humid climates
Research "seem"to indicate that ammonium nitrate
is certainly a factor in the inflators ruptures
Kennedy conceded ,But "There are indeed many other
factors.
He mentioned the lack of desiccant to keep the inflators
dry and the shape some of the ammonium nitrate
wafers inside the detonators as additional factors.
Kennedy said Takata and other parts makers have
stepped up production of replacement airbags and
inflators to reduce the dangers ,but many of those
from Takata still use ammonium nitrate.
Over time ,Kennedy said they will replace the
chemical with another
I think over all you will see ammonium nitrate
production go down he said,
