Abstract

In making gas-expanded rubber the dough is at atmospheric pressure rendered plastic and simultaneously partially vulcanized by heat, and then gassed. The gassing cylinder may be preheated to the same temperature as the dough, e.g. 180-200 DEG F., before the introduction therein of the latter. The dough may contain two accelerators, one of which becomes active during the period in which the dough is plasticized &c. by heat and the other by the greater heat of the final vulcanization of the expanded rubber.
