ABSTRACT:
An improved process for vulcanization of elastomer products which includes the steps of heating under pressure, the elastomer product mounted in a metal mold by supplying vulcanizing medium, suspending the supply of the vulcanizing medium when the elastomer product has reached a predetermined temperature or passed through a predetermined time period, and subsequently supplying insert gas preliminarily extracted from atmospheric air and maintained at least under approximately the same pressure as that of the vulcanizing medium, up to the termination of the heating step so as to maintain the elastomer product at the predetermined temperature.
