Introduction-
Foaming MB 7300
is particularly adapted for use in unicellular procducts where
low gas loss be diffusion is required since it blows by releasing
nitrogen.It is non-odorous in itself and imparts no odor to
the finished products for which it is used and may be used
in white or light colored compounds without the objectionable
discoloration and staining obtained with many organic chemicals
although it is a yellow pellet, the decomposition residue
by heat is white. 7300 is broadly used blowing agent for most
polymers processing, and should not be used with beryllium
or copper tooling in injection molding structural foam.

STORAGE STABILITY
AND WASTE DISPOSAL--
Foaming MB 7300 has good storage stability and will remain in
a good condition provided it is kept dry, cool and away from
any sources of heat close to decomposition temperature(190℃).
7300 should also be kept away from strong alkalis with which
it reacts .Dispose of approved chemical disposal area. |
