Government says Boric
Acid Leaches from Mattresses
“9. Permanence of
Fire-retardant Formulations
Of special interest to
the corrections community has been the issue of permanence of fire
retardants in mattresses. A significant fraction of current-day correctional
mattresses use boric acid treated cotton batting as the core material.
This treatment is impermanent in that it is subject to both mechanical
segregation and leaching. Thus, part of NIST activity involved
developing a leaching procedure and subjecting all bench-scale specimens to
Cone Calorimeter testing under two conditions: as-received, and leached.”
