Generally, foaming agents are the substances forming
pores or cells in the material. Among them, chemical
foaming agents are the compounds which decopose
with the generation of gases when heated within
a fixed range of temperatures. The foaming agerit is
realized by making use of such gas generating characteristics.
Azodicarbonamide, one of the typical chemical
foaming agents, is generally not easily soluble in solvents
or ester plasticizer, but its foaming work can be
effectively achieved since it is diffused with ease in
rubber or plastics in accordance with conventional
mixing methods. The foamed products are characterized
by being odorless and not subject to contamination
or discoloration. |
