Premium powders powering performance.

Characteristics of Boron Nitride

/
  1. Based upon certain laboratory studies, BN powder was considered non-toxic at certain levels of oral, dermal and inhalation administration.
  2. Based upon certain laboratory studies, BN powder was considered non-irritating and non-sensitizing at certain levels of ocular and dermal administration.
